I already have the aspi layer (even though it is 4.71 while everyone seems to love 4.6)
Everyone loves 4.6 because it works. Don't count on discdump (or anything else for that matter) working with 4.71.
I think its the virtual clonedrive (ccd) that's scrwed with my comp.
Quite possible. It screwed my comp quite effectively the one time I installed it. Problems disappeared as soon as I removed it though.
