I just installed the 5.1 version over the 4.5 version on ASP.NET 1.1 (cutesoft Editor) 
I deployed everything onto my server
1)The entiere Cutesoft_Client directory
2)binaries:NetSpell.SpellChecker.dll and CuteEditor.dll

On my local machine everthing works fine. But on the server an error message shows up.

In this case its when I click on the ColorPicker. But it also gives an error if I pick on the "Smilies" button.

Thanks for helping

Michael
