That happened to me once when i updated MsgPlus i just re-installed the old version and it worked again, have you restarted your computer and then checked if it works?
The solution from the stuffplug forums, for other people with this problem:
quote:Go to Start>Run and type in regedit and press ENTER.
At your left you see some different 'HKEY' directories. Doubleclick on 'HKEY_CURRENT_USER'.
Then doubleclick on the directory Software, then Patchou, then MsgPlus2, then the directory with your email in (for ex. bill_gates@hotmail.com), then Preferences, then Plugins.
From there you click only once on the directory stuffplug-ng.dll.
You should now see in the main window alot of registry keys. Search up the registry key called "Enable" and doubleclick it. A window comes up called Edit DWORD Value.
Write in a "1" (without the quotes) instead of the "0" that is there.
Well done! You should now restart MSN then SPNG should load. If SPNG fails to load once again just do the steps again.
