I upgraded to GT 188.8.131.52 from 184.108.40.206, directly without uninstall.
I lost my cache. I had a backup copy of the 220.127.116.11 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?
