hello, can you help me? I have 4 fredo licenses, but non of with it's working.
After a recent Windows update, I’m getting the ERROR_A04 ("Wrong Signature File") when trying to validate my license. I already deleted the signature files, updated the extensions, and ran SketchUp as administrator, but the issue persists.

Hello,
I’ve been a customer of yours for years and already own several plugin licenses. Recently, however, I’ve been experiencing an issue with the JointPushPull extension. My license seems to have a problem—whenever I try to use or manage it, I receive the following error message:

ERROR_A04
Wrong Signature File – You may have changed the computer name
It is advised to erase the Signature file and revalidate.

I’m not sure how to fix this. Could you please help me resolve it?
