so just a thought...why not consider re-downloading your TacPack purchase from your VRS Customer Page... possibly updated, and re-install TacPack in your FSX-SP2/A or FSX-SE install; and perhaps the issue will resolve itself
per this thread, it appears simconnect was updated for FSX-SE:
https://www.avsim.com/forums/topic/497361-fsx-se-installing-simconnect/ to v10.0.62615.0
and per this thread, it appears FSX-SP2/A has the simconnect you are struggling with:
https://www.avsim.com/forums/topic/570908-the-bear-fsx-simconnect/ --> v10.0.61259.0 --> not the most up to date, and perhaps no longer compatible with TacPack??
cheers!
