First at all you have to excuse my poor english
now i had the same problem after reboot i wasn't able to found plus.so I have switch my ad-watch to manual mode 'nd i've discovered that it was stopping any changes in the registry at the voice of messenger so windows every time had to load (not sure about this is correct
) the "normal" version. So probably you have some software for registry protection. in this case you can
1) Do the changes in the registry manually (very bad thing)
2) Switch the softwar to manual control and grant the permission to change the registry key after you install plus! (it seems that plus change the same key in the register evry time you start it)
3) Unistal software for registry, install plus, reboot, reinstall software for register
hope i'm right
Another thing when i had the problem of uninstall i had 2 user in win. i had to cancel the second one (for other reason) but don't thing this is a matter.
Bye 'nd sorry again for my "Maccaronical" English
