crash to desktop

[unknown]

I had some ctd's the last 2 months in DCS 2.1.x, not Viggen related. I think that was a problem with a beta gpu driver, didn't had much problems with that after installing a new gpu driver. But now i'm flying the Viggen more often and finally try to learn and master this beautiful aircraft but i get some crash to desktop with this module. This happens sometimes in single player (2.2 open alpha and 1.5.8 open beta) and everytime there is the "AJS37-Avionics.dll" mentioned in the DCS crash log. I also was flying in multiplayer yesterday for the first time, trying the Viggen anti ship capabilities and had several ctd's that day. Some were after i released the RBS15, some flying to the ships and some were just flying around. So nothing to reproduce the problem. I did a repair of my DCS installation yesterday. I did a little bombing training today and after landing while taxiing to the parking position for a rearm DCS crashed again(1.5.8 open beta). Attached is the crash zip created by DCS. Are there any known issues that i can avoid to prevent DCS from crashing with the Viggen because i like this bird very much and would like to learn and master more of it's systems but all the crashing is a little fun stopper.
