Ok .. as you said .. there seems to be a problem with your APPZ Folder .. Try to run a scandisk .. OR rename your APPZ to "APPZ_old" AND make a completely new folder named APPZ .. maybe somthing wrong with your filesystem...
Good that (expect for APPZ) all seem to be working!
I was on my way to the bed to sleep... BUT instead i stayed up and wrote som test programs that i think will solve the DATE issue
