Crashing once running to a certain area

[Weeble]

I am having a problem walking to a certain area in the game. I can log in fine, play the game fine, but once I walk to a certain point in Ostland I just suddenly crash. I've tried walking to this area with different characters with the same results. The crash happens on the left side of the Ostland map, near the Gore Wood PQ(14127, 57788). It's as if there is an invisible wall that I can't go through, the same happens coming the other way on the road above it.

The only error message I have gotten after trying multiple times to get to this farming location was this;
Data.myp:
System.Exception: You need to stop application currently using the following file: data.myp
at MYPHandler.MYPHandler.WriteFileToArchive(FileInArchive archFile, MemoryStream MS)
at MYPHandler.MYPHandler.ReplaceFile(FileInArchive archFile, FileStream newFile)
at RoRLauncher.Client.UpdateWarData()

Could this be a memory problem? Should I just reinstall the game?

I've tried turning off the read only tick, and running as admin, as well as moving the folder location. Still no go.

Please help if possible,
Thanks
