I was having some of the same issues :| I ran TO 7 times all of them failed and on the 7th time it crashed my computer and blue screened it. That was last week and after that I pretty much quit TO. Even though I put nearly 6 years into this game and a bit to much money, it's not worth crashing a computer over as you said spamtastic. I hope things go well for you though. It's pretty much the same here as well.
Currently playing, League of legends, and Audiosurf.
