hi,
i had a similar prob. pt10 imac osx 10.7.5 this post didnt help me:
http://duc.avid.com/showpost.php?p=2074556&postcount=37
I ended up going here:
http://avid.force.com/pkb/articles/e...755&popup=true
and i followed the instructions and changed the big file but then couldnt load just the xpand disc, because i got the 003 factory bundle. I never had the probs other peeps were having with it telling me to find the .big file. my xpand would load fine and i could see all the samples in the drop down box but it wouldnt load into the "parts" box.
after I did the avid force instructions then I would get the notice to find the .big file. it was always where it shouldve been before but still wouldnt work. now it wasnt in the same location applications/avid/instruments etc. i thought i was screwed. under my finder "edit" i chose "undo move" but the .big file wasnt back under "avid" so i searched in the finder. I found it and copied it under the avid/virtual instruments, where it always was. then i went back to PT and still had the browse window open for the big file. i browsed under the applications/avid/virtual inst and it works!!
ive been messing with this on and off for a couple weeks and im stoked to mess around with expand. I just hope it works when i restart my mac. im more of a musician than a computer guy, but hope this helps somebody else.
