So I made sure to have WOT steam version installed on my C drive same as 165 version of tank exporter I made sure to update and everything.

But I am getting an error anytime i try to load a tank
unhandled exception index was outside the bounds of the array

Here is the full Error log

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:

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.

I have never tried this with the steam version.
I am not sure if it will work.
Try the direct wot version from their servers.
