Hi everyone.
I found a solution to the issues I was encountering. This is how I solved it:
1- Used Javed's recommendation about going to File->Preferences->Excel Options->Maximum Number of Rows and changed the limit.
After doing these changes Xcelsius wouldn't let me export the flash file causing the software to crash or freeze for no reason at all. Fix:
Optimize Spreadsheet: Uncheck the "Enable" Box.
Hope this helps.
