Nobody: that's german, not dutch. Of course that little program was made by a super 1337 german coder :-)

"Überprüfe die Datei ...Datei ist ok.
Die Datei wird jetzt gepatcht...file0001.exe kann nicht gepatcht werden. "

Translation:
"Checking file...file is ok.
Patching the file...file0001.exe can not be patched!"


Seems like there is something wrong. Maybe you should let someone else patch it for you, like Overlord said.
