Loading database failed

Go into your league folder, and renaming any files that end in *.bak to *.dat instead. For any file that has both a .dat and a .bak version, delete the .dat and rename the .bak to take its place.
(What's going on there is that as soon as OOTP finishes downloading a league file, all the league's .dat files are renamed to .bak files as a backup. With your corrupted league file, new .dat files aren't being extracted to take their place, so OOTP thinks the league is corrupt because of a bunch of the .dat files seem to be missing.
So "restoring" the old versions will get their leagues up and running again)"

Hope this helps
