Hi
I think you should try the following once :-
FIRST OF ALL, DISABLE YOUR ANTI-VIRUS AND THEN FOLLOW THE STEPS BELOW, AND AFTER EVERYTHING IS DONE, THEN ONLY ENABLE YOUR ANTI-VIRUS
1) Completely UNINSTALL your "NOW" program, preferably by using the software "YourUninstallerPro" so that all the registry entries etc are gone too. Link to download this program is given at Pt#5
2) Then restart your computer
3) Then install "NOW" and while installing, change the location of installation from C:\Program Files\NOW to C:\NOW
4) Then try to login, hopefully it will do the work for you. (As everything was gone while uninstalling, so "NOW" will take some time after 30% during login process to download all relevant files as it usually does)
5) The link to download YourUninstallerPro program (in a WinRAR file) is http :// w w w . 4shared.com/rar/gBNKeewT/Your_Uninstaller_Pro_74201110.html (REMOVE THE SPACES FROM LINK). You will also get a Text file in which you will find the Registration Details for the software written at last.

PS : Mods, I think that giving the link for this software is OK with TraderJi for the benefit of all, but if not, then please delete the link from that post .......
