I upgraded to GT 220.127.116.11 from 18.104.22.168, directly without uninstall.
I lost my cache. I had a backup copy of the 22.214.171.124 cache. But if i copy the files in the new cache folder (gt-cache), i receive this message:
cache: deleting BAD cached version .
Is there a way to preserve/copy the old files to the new cache dir without deletion?
