I released an update of FredoScale, v3.5a.

I removed the expiry date so that it does not happen again (I just forgot to do it).

version 3.5a works. Thanks!

I have been using FredoScale fine. Today when I launch FredoScale I got error "This version of FredoScale has expired. Please upgrade to latest version.". I checked and confirmed my version is latest (3.4b). I tried download and install again, didn't work. Also unintall FredoScale and reinstall, tried Sketchup Pro 2021 and 2022, none works. btw I purchased FredoScale bundle licenses and activated successfully before.
Appreciate any help.
