Need Help - Reindexing Blockchain

I need help here, for the last 5 days in a row I've been trying to download the Blockchain on Bitcoin-qt so that I can run Armory with offline transactions from my Raspberry Pi. Everything is already setup on my RPi, now I just need to download the block chain on my Online Armory client. This is proving harder than it looks…
I'm running my Online Armory client on Windows 8 OS booting from Virtualbox on my Mac OSX. The reason I have to use virtual box is the latest version of Armory for Mac glitches out and doesn't work for me.
So I've downloaded the bootstrap and placed it in the correct location and ran Bitcoin-qt, at this point (after 20-30 separate attempts) I've downloaded up to around "15 weeks behind" but once I get to around October 22nd, 2013 the blocks begin indexing extremely slow. I've tried booting the qt client with -reindex commands several times, I've tried booting qt with the -dbcache=1000 commands several times, and unfortunately I STILL have not completely downloading the block chain and I'm about to fucking murder someone because it should not be this difficult to download the block chain!!
So each time when I'm downloading the block chain it gets interrupted by one of two things. FIRST, sometimes around 15-14 weeks behind the qt client just "stops responding" and windows give me the option to close it out. After I close it and try to reboot, the database is unable to be found and I have to run the -reindex command and start all over. The SECOND thing that happens, is my Windows 8 OS running on virtual box will randomly go to a new screen that says "your product key is not correct, please enter a new one or buy another"… even though I initially entered a working product key when I first installed the OS and when I try to reenter another working product key (I've tried dozens) none of them work. So this blue screen interrupts my block chain download and at this point I haven't got past "15 weeks behind".
I've tried saving snapshots so that when the qt client stops responding or the windows 8 OS goes to that blue screen that says "reenter product key" I can restore from my last snapshot, but when i restore from an old snapshot one of those two problems continues to occur and prevents me from downloading any further than block 265502.
At this point I'm for a loss. I've done hours of searching and can't figure out how to fix this shit… can somebody help me out?

A new --disable-bip70 option may be passed to ./configure to prevent Bitcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Bitcoin Core to libssl vulnerabilities in the past, builders who don’t need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities. That is one of the bitcoin blockchain’s most attractive qualities — it is so large and has amassed so much computing power. At time of writing, bitcoin is secured by 3,500,000 TH/s, more than ... I have heard of one case where Windows was extremely slow with writing files if you do it wrongly. (This has nothing to do with Qt.) The problem in that case was that the developer used a SQLite database, wrote some 10000 datasets, and did a SQL COMMIT after each insert. This caused Windows to write the whole DB file to disk each time, while Linux would only update the buffered version of the ...
