I upgraded to GT 22.214.171.124 from 126.96.36.199, directly without uninstall.
I lost my cache. I had a backup copy of the 188.8.131.52 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?
