I just downloaded the open Beta for 1.5. Out of the modules I have, only four are available (F-86, TF-51D, Mig-15, and SU-25T). I am running Windows 10. modules available should include the previous as well as Flaming Cliffs 3, A-10C, KA-50 2, Huey, Combined Arms, BF-109, FW-190, P-51D, Mig-21 and SU-25T.
After refreshing Module manager, I get the message "An error has occurred while receiving data, try later."
Modules I've previously purchased are available to buy but not to download as if they were never purchased. dcs logs.zip system.zip
