I've been having an issue with my Archicad key where the License Manager Tool does not allow me to upload and download that specific Arch key. It seems to be that the issue is: the key is permanently stuck on the computer or the license manager giving me an error message like the one I've attached as a screenshot.
Since I cannot access that key, I can't upload it for someone else to use it, but it still allows me to normally use Archicad with no key-related issues.
Refreshing the page doesn't do anything and neither does signing in/out. Does anyone have any suggestions or ways to fix this issue so I can upload and download the key as it should allow me to do?
