I just upgraded from 5.0 to 5.1 and now whenever I try to open a workbook, Toad crashes. Details below:

“Toad Shutdown

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!

Thank you!

This is a really uncommon issue. You can try to remove your application data folder which we are using for storing setting information for Toad.
C:\Users****\AppData\Roaming\Quest Software\Toad Data Point 5.1

Try to remove it and start TDP again.
If you still have an issue please go to this AppData location again and try to send us file 'ExceptionTrace.log'

Thanks for the tip, Filip. I am a little confused about the implementation. What do you mean when you say "remove" the application data folder? Where should I move it to? Should I delete it? Cut and paste it to another location?

Thank you for your help!
