OCTGN

Previously, I could run O2 executable twice and play 2 games at the same time. Since the upgrade, I cannot join or host another game when I have an instance running. The 2nd instance will generate this crash message:

System.IO.IOException: The process cannot access the file ‘C:\OCTGN2\a6c8d2e8-7cd8-11dd-8f94-e62b56d89593\Magic-v0.0.2.3.o8g’ because it is being used by another process.
