I have seen “The index was out of range. It must be non-negative value and less than the size of the collection.” However, I still don’t know where the “Matrix dimensions exceed the admitted range” message could be coming from. There should be a stack trace under the error message that looks something like this:
---- Stack Trace ----
openPDC.exe: N 00380
openPDC.exe: N 00357
openPDC.exe: N 00801
Can you provide the stack trace?
