I would like to know what is the best version of pol to run UOHS?

I've got the two versions bellow installed at the moment
UOHS 7.0.15.1 path 51
UOHS 7.0.16.3 path 53
UOHS 7.0.24.3 Path Unknown
polserver - Revision 525




https://polserver.svn.sourceforge.net/s ... polserver/

use the last build from svn

i would like to know why uoconvert.bat Revision 525 isn't working with UOHS 7.0.24.3 Path Unknown

Short answer: OSI changed the file structure and now none of the old tools like uoconvert, uofiddler and others work, so don't bother with using client 7.0.24.x.

Use any earlier version for now.
