Dear Team,
I'm using zenon 7.60. I face the following issues when opening VSTA,
1. Complete VSTA program getting deleted.
2. Unable to open VSTA.

The above issues are faced under any of the following conditions,
1. Any error in windows form.
2. Any error when building the project in VSTA. Under these conditions if I build the project and create a runtime file, the next time when the VSTA project is opened I'll face any of the issues mentioned above.

Kindly provide me a solution and also the cases under which these issues might occur.
