What the message is saying in english:
Windows Cant find the file KnightOnline.exe. Check if you spelled the name right and try it again. Click on search if you want to search a file, Press start and use the Search function
(My english is pretty bad, but I think this is the best english I can make from it.)
I hope someone can help me.
Ty in advance,
(PS I installed KO correctly into C: Knight Online and I have all the patches and moradon expansion)
