I'm getting the following error most of the time when I open Studio, but sometimes it doesn't & sometimes I get an error when I try to save the project.

Unhandled Exception has occurred in you application.
Bad Method token.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

The following is from the windows logs\Application errors at the same time:

I appear to have the following .nets installed: 2.0, 3.0, 3.5, 4, 4.0, 4.7

I included my project file, in case it is corrupted.
