Hi Eslam,
I advice you to try the following:
-Make a back-up of your Plus! preferences:
Preferences and Options > at bottom left import/export, follow instructions, check all the options in the panel minus the last two (plugins ad skin settings).
- Uninstall Plus! completely, meaning including preferences and plugins....leave them two boxes in the uninstaller checked.
- Uninstall any other Messenger add-on you may have
- Uninstall Windows Live Messenger
- Reboot to make sure there are no leftovers
- Go to
http://explore.live.com/windows-live-messenger and redownload/install Messenger
- Install Messenger Plus! from
http://www.msgplus.net/
After that if all works correctly you can import your settings again (Preferences and options, bottom left Import/export). If all still works ok after that you can look at installing skins, plugins etc. from our databases,
http://www.msgplus.net/Downloads, should you so desire.
If after all these steps, please do follow them carefully, it is still not working as should and you get that box again you can always check the box in front of Disable Safe Mode even tho that does not help us determine where the problem lies, it should make Messenger Plus! run.
Please post back to let us know if you managed to solve the problem.
