Ragnarok Online 2 error - RagII.exe file mix-up

I was playing RagnaroK Online 2: Gate of the World and the file RagII.exe is apparently being recognized as the game Red Orchestra: Ostfront 41-45 instead. http://wakoopa.com/executables/ragii-exe says that the fiel RagII.exe qualifies under both games Ostfront 41-45 and Ragnarok Online 2: The Gale of the World even though that is utterly incorrect in the first place.
