May i point out that changing one password means it changes the Control Panel, Cpanel and the Forums password too there is no way of changing just the CPanel one.
And on that note i myself am unable to login to my Cpanel and i was able to about 3-4 days ago and it was te password im currently trying to use.

Ingor the fact i can't get in now as i just managed too with the same password
must have been on the blimp or somthing
