Nevermind about the error messages.
I coppied the following files from development to the live server and it started to work again.
CuteSoft.Chat.dll
SamplePortal.dll
SamplePortal.pdb
But when I was coppying them I noticed that they had the exact same date modified and same size.
If its stops working again I think it has to be related to the licence. isn't that how your licence works. The code starts out working and then stops working.
