Hi,
I bought the perpetual license for round corner a while ago and it was working fine till now, It stopped working entirely today, so I updated all the plugins including libfredo6, sketchucation, to make sure they are up to date. I also reinstalled roundcorner, and I validated my perpetual license, which worked initially, after I used it for one minute though, it told me i need to validate it again, but then it wouldn't validate successfully, it keeps on telling me "error, wrong license id", so now I can't use the plugin at all. please refer to the screenshot attached.
