I have got these a few times in 7.02 and I thought they were file manager related, but I just got one dragging a drum rack (containing 3 chains assigned to one pad) to a pad on another drum rack - bang!

[edit:]

on reboot I tried to recover the set and got: "...Apparently this document was created by a more recent, incompatible version of Live than this"

and then:

[Missing compound model for Class "TrendPreBool"]

and when I clicked OK Live just quit

get that damn compound model in there boys! I mean it!!!

the set became corrupted and I could no longer open it - but I found a copy and opened that then saved under a new name, then attempted to drag the same drum rack (containing only 3 chains pretty much the same) to a pad on the other drum rack and got the 'serious program error' again

this time tried to restore from undo and Live just quit without warning

now I got the serious error just when trying to group the drum rack containing the 3 chains with a saturator and compressor

it doesnt like this rack

I have just yesterday bought a new external hard drive and reorganised a lot of stuff including uninstalling some live packs from my internal Library and then creating a new 'super library' on the new hard drive

I have set the new library as my current one, but the problem set/rack is on the previous internal partition so in theory there should be no difference
