I have runned registry fixes, but no difference.
But I totaly phisicaly deleted the program. History: If I try to install again the copy through the setup it tells me that 'Previous version of Netlimiter was detected, please uninstall first'. What makes matter worse is that it still applies it's setting to certain programs, limiting my bandwith usage by those programs. Then I remembered the program is set up in add/remove programs. I have Netlimiter installed for some time now, when one day gave me a 'Check Faild' I have then somehow deleted the program for a reinstall, but I did not deleted it as normaly, from add/remove programs, I just went to my HDD and physicaly removed it (Shift+delete on the folder).
