Free Trial Viggen module missing despite being installed.

[entropyembrace]

I activated a free trial of the Viggen through the DCS free to play program. Initially the module worked but training missions were broken but now the module does not appear at all despite being installed. There is no Viggen in instant action, campaign, training, missions. It is also missing from the bar on the bottom of the title screen.

I have this exact same issue, no idea how to fix it. 

 

Edit: I fixed this by disabling Malwarebytes, thanks to the help of support.

Indeed, please check if malwarebytes has blocked any of your DLLs. (or any other antivirus or anti malware program)
