I've been running the 2nd to last developer release of 10.6 for a while. I just now accidentally downgraded to 10.5.6, then installed the latest developer release of 10.6 (10A432) over 10.5.6, and now I can't access any of my old files. All the folders have that red "permission denied" icon on them. When I try to open a folder it says "The folder can't be opened because you don't have permission to see its contents." All my files are there, I just can't use them. How do I get access to my files? thanks.
