we have a problem with a patch not opening any more. it was working for years without problems. as far as i can see, the patch hasn't been modified at all, also the system hasn't been changed (no software or hardware modifications). the problem is on win xp and occurred with max/msp 4.5, today i updated to 4.6 to see if that by chance fixes it, but the error still occurs.
while max can be normally launched, when the patch is loaded, a window pops up saying
"Microsoft Visual-C++ . Runtime Error! Program: C:ProgrammeCycling '74MaxMSP 4.6max.exe . R6025 - pure virtual function call", and an "OK"-button. if i press ok, the dialog pops up again. After clicking 35x on ok max quits. that's it.
Trying to trash the preferences didn't help.
what can i do?
