Xigncode3 crashes game.

Starting playing again after being away for a very long time.
All the updates went through well and I played for a bit today without problems. However when I logged out it gave me the error:



0xE0191014
Error: Xigncode3 detects executed game client als multi-times.

At first I clicked it away since it appeard after I closed the client and it didn't interfere with playing. However I tried logging back in a few hours later and now
once I logged in it gives me about 5 minutes before it kicks me out by giving me this error.
I tried looking at the log, but this error is not listed in that log.

Any ideas how too fix this?
