MiG-21 Is there a fix for DLC?

Its been so long and I cant believe that I still have this problem. Every time I fire up DCS I get the MiG-21 error message. Can someone please point me to the fix? Sorry if I sound frustrated. I am. I really like taking the 'ol MiG out for a spin once in a while and I miss it. Hope this gets sorted out once and for all.

Thank You Sir!
