I'm afraid this might be my computer rather than SimPE, but I don't know. I've been making skins and I find when I am trying to extract GMDC files from the game I keep running into a problem after I paste in the instance number, get the file I want to appear and then click on it. I have to shut down my computer and start again to get the file.

I have tried hiting "continue" but then I ended up with a bad GMDC.
Thanks

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (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 machine
rather than being handled by this dialog.
