Careful fix: Slow but your settings are preserved and few downloads lost.

1) Check for a corrupted resumeinfo.txt
•All JOB tags should have 9 lines of stuff before the first SEGMENT tag.
•All SEGMENT tags should have 4 lines before the next SEGMENT or HOST tag.
•All HOST tags should have 7 lines before the next HOST tag or the end of the file.

If any of these are messed up, delete the last JOB in the file

2) Check for invalid registry entries. Go to Start -> Run -> Regedit and find HKEY_CURRENT_USER\Software\Xolox and compare the following entries:

key ------ my setting ------ valid settings ------ use (when 1 if not otherwise noted)

sockslevel --- "" --- ??? --- I don't use a firewall, if you do, then procede to the semi-drastic solution section.
sockspassword --- "" --- ??? --- ""
socksport --- "" --- ??? --- ""
socksserver --- "" --- ??? --- ""
socksusercode --- "" --- ??? --- ""

Semi-drastic fix: may have problems if you have a corrupted resumeinfo.txt file, but fixes any registry problems. All user settings are deleted.

Delete the key: HKEY_CURRENT_USER\Software\Xolox and start up xolox, re-set your settings.


Drastic fix: Fast and easy, it kills all of your cirrent downloads. (back up your /downloads directory first)
Delete your XoloX directory, delete the Xolox registry entry, then re-install XoloX.
