If you only use one account, the change can be made in the registry.
Open the registry editor (regedit.exe) and go to HKEY_CURRENT_USER\Software\Patchou\MsgPlus2
There you find a key called DefaultConfiguration and the value will be your old account name. Change that value into your new account name and event logging will work for that account, but it won't work for your old account anymore!!!!
