unhandled exception

What steps will reproduce the problem?
After making a "new arduino" I clicked clone (I clicked it because there was no
graph, the program doesnt seem to work) and it poped out this message:
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.

it seems that the program throws this exception when I try to open menus once
created the arduino

I think this error is caused because the graph isnt generated until the first
voltage read

Well.. Maybe I found the origin of all those exceptions.. Maybe, it is that for
some reason, the oscilloscope doesnt start until there is a significative read
in the arduino board, so the window wont work, and neither the controls (today
I tried to use Xoscillo and it worked, not as yesterday)

Also, your program only works with "well built" circuits, when it triggers the
"tools" (as decode frequency) will work, otherways it won't
