Sorry only one instance allowed after Ka purchase

[skc]

I recently updated DCSWorld followed by on 20th Dec buying the Blackshark 2 which ran O.K.

Now after returning to the game after short absence when I try to start either the paid for modules, A10 or KA they will not run and I get a "Sorry only one instance allowed".

 

Any guidance on sorting this out will be much appreciated as I really want to fly!:(

 

Thanks in advance.

try repair dcs.

I solved the problem...I had initially opened the Multiplayer instance when I actually wanted the DCS instance. I then opened the DCS instance without realising the multiplayer instance was still open!....'Embarrassed!':)
