FS2004 Startup Issue

[Z-AZ1USN]

Help!!!
Lately when the FS2004 splash screen appears there is this tiny box that reads "unknown name". I can dismiss it and FS2004 will continue to load.
It's a speed bump of sorts that I can't seem to find the fix for. Any ideas out there? Thanks in advance......:isadizzy:

Have you installed any add ons recently? Planes? Scenery?

I think this message may be associated with something related to an add on.

If you did install add ons try deactivating them one by one and see if the message stops appearing.

Can't think of anything else.
