I'm not too good with computers, having trouble with FairUse

So i'm interested in using FairUse4wm, but i'm running into a few snags regarding using it, and frankly i have searched for answers but i don't understand most of the lingo on here, so bare with me...

i downloaded something called mirakagi and it has mirakagi and FairUse in it, when i double click on FairUse to use it, it says no keys loaded, and then recover keys, when i press that it says IBX compnents do not appear to be present so i press ok and it says attempting to recover DRMv1 keys, fairuse will use a wm-installed dll to determine system specific information, then it says "drmclien.dll" has version 9.0.0.3250

so that gets me no where so i check out the mirakagi program. i press start! and it processes, says succeeded, 0 files, 0 keys, mirakagi starts, code version .9, found 0 keys in keyring, it is finished

so i have no clue what to do to use FairUse, while im not computer retarded, im no genius either, so keep that in mind

if anyone can help me out i would be eternally grateful
