I tried out the 750 Premium with the Arrow yesterday, before the WASM hotfix was pushed, and it worked great.
When I installed the hotfix this morning, I did due diligence, and renamed my Community folder. After it booted once, and worked, I then moved my addons into the new, empty Community folder.
The 750 reported that it needed to be re-activated, so I retyped my license, and I got this message when I tried to activate it:
I double checked my license code, and it does appear to be correct. So I assume its the site. Has the site changed between patches, and the check would show my license having already been used, so it thinks this is a stolen copy perhaps?
Maybe I should have extracted a fresh copy, not move the previously activated copy?
