Thanks for all the replies guys, I did manage to get my game to run in A8 after months of converting code but I had to abandon it because it would run fine if I ran it from WED but once I published it and ran the .exe it would crash to desktop without warning so it was a dead end. I will contact support to see if an A8 key is compatible with A7 if not I will try to convert it to work with A8 again.
I still have A8 on my computer I can do a YouTube video to show how A8 crashes if you like?
