Corrupt pk3 files is the cause. Check the file sizes against this list. This is what the pk3 file sizes should be: UO 1.41 pk3 file Sizes: localised English pakuo00.pk3 123,141,455 bytes pakuo00.pk3 162,980,955 bytes pakuo01.pk3 165,818,400 bytes pakuo05.pk3 725,304 bytes pakuo06.pk3 238,582 bytes Added from 1.51 localised English pakuo01.pk3 72,866 bytes localised English pakuo02.pk3 3,772,796 bytes pakuo02.pk3 166,227,647 bytes pakuo03.pk3 146,286,848 bytes pakuo04.pk3 163,831,126 bytes pakuo07.pk3 3,129,841 bytes What ever file(s) don't match with this list replace by exploring the UO CDs, look in the folders called 'Data', then copy and paste the offending files into the 'uo' folder in the COD directory. Make sure the CDs are free of marks or scratches. Also clean your ROM laser heads with a head cleaner.
Didn't work. :(
What didn't work? You need to be a bit more detailed - what did you do? What files needed to be replaced? Have you reinstalled?
I've reinstalled it twice. I compared both pk3 files and even retried all of that and installed the patch.
