Hi Evan,
Please post your ticket number here so I can follow up for you. Regarding the messaging you receive, please let me explain a bit;
GrimeFighter does a pretty extensive check of the PC HW, registry, disk, etc.. when it begins the process of booting into Linux (at the beginning of the cleaning phase). If it finds anything that looks to be in an unexpected state then it backs out rather than cause any damage to your PC.
Because that issue could be a number of things (and quite technical) we provide a kind of generic error message there. I agree it is not informative as some would like.
One additional remark, in late January we will be adding a function which does this PC check before purchase, thus avoiding exactly this issue where you bought it and then discovered it won't work which is obviously not a good experience and one we need to (and will) improve.
Thanks,
davidek
