I just upgraded from 5.0 to 5.1 and now whenever I try to open a workbook, Toad crashes. Details below:
Toad encountered a serious error and must close.
Please save your data and close the application.
We apologize for the inconvenience.
Binary stream ‘0’ does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization.”
Any help would be highly appreciated!
