The error message pretty much says :
A fatal error has occurred.
Module: FILEPATH\Sampletank 4.dll
A crash dump file has been created.
Exception code: c0000005
Address: Random numbers and letters to show where in RAM the error took place
As a result of this error Cakewalk is about to exit abnormally. Would you like to save your work?
Looking around it looks like c0000005 means Sampletank 4 is trying to write something in a location it can't access. If anyone could give me some advice or ideas on h ow to solve this I would be grateful
