I bought A10C on Steam Sale. Ran it couple of times, then realized whole DCS community has moved to DCS world. I downloaded it, uninstalled Steam version of DCS, downloaded A10 module for DCS World but when I try to activate it using the key from Steam, I'm getting the 'Invalid Hardware Code. Make sure the Serial Number used is valid for the product you are trying to activate, generate a new Hardware Code and try again.' error. How do i fix this? Tried running activation program straight from the module folder as an administrator, didn't work. Neither did activation via Starforce website - got the same error.
