I have just bought and installed REX 2.0 and REX OverDrive_FSX_20101027. I'm using FSX Gold Edition with Acceleration & SDK. W7 64bit. i7 and 6gb RAM.


When I start REX 2.0, load a plan and FSX opens,  I receive an "Unhandled exception has occurred in your application" error box.
When I click the 'continue' button, I get another similar error box with Microsoft.NET Framework as a header, and eventually, a dialogue box saying REX Weather Engine 2.0 has stopped working...Microsoft is searching for a solution...   

I have uninstalled and re-installed REX as administrator, uninstalled my anti-virus, disabled my firewall to no avail.
Weather textures are loading into FSX but the weather engine and Weather avoidance don't seem to work and generate the 'unhandled exception' error messages.
Any guidance or suggestions appreciated.
John.

************** 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.
