Hi, I bought the game on GOG and it has ran fine without any issue until today when it suddenly started saying it needed Adobe AIR. I downloaded and installed it just to be sure but it still says I need it. Any help?

Looks like something went wrong with the installation. While Adobe AIR was originally a dependency that had to be installed separately, it now comes as part of the DQ package - in the directory with DQ, there should be directory tree Adobe AIR directory/Versions/1.0 - and in there the Adobe AIR.dll itself and a Resources directory with more stuff.
I just tried the current GOG build and its Adobe AIR is 20.995.432 bytes, dated from 10th February this year. See if you can find yours - by what you're saying it looks like it might have gotten deleted/corrupted.
