That is the error you get when you change the trose.exe file from one client version to another without also copying over the necessary dlls
i assume you did this while patching an evo client to run in rev80.. right?
I haven't done a patch for a while so i'm a bit rusty
In order to do such a patch you need trose.exe, TGamectrl_r.dll, znzin.dll and possibly triggerVFS.dll
All the files should be in the zipped patch file that you got with the trose.exe file
