What is causing this, please?
This has been discussed many times on the forum, and it's just a generic panic message from the sim, if it cannot load the module for any reason, usually because you are missing some system libraries, but also because of conflicts caused by other modules using different version of the needed libraries (either Simconnect or VC++)
Sometimes it just goes away by simply allowing the module to run, even if it says it might not work, and try again. Sometimes it goes away after a Windows restart.
