Hi, we have updated to Reckon Accounts 2014 and it is on a server and was working yesterday with multiple users but this morning we are having issues, we can use it on the server but no-one else can login or if it's not open on the server one other person can use it but it is in single user mode and cannot change to multi user mode (we get an error message about the host protocol) I have had two different error messages - (-6000, -80) and (H202) when logged in to the server only I can see where there has been transactions done today, I'm confused and my IT guy has gone on annual leave today and I am not very techno minded

can anyone help please
