Platform Error - Going from Custom to PVP Games

I have this error that has existed before, and now has returned again. If i am in a custom game room, then exit and try to launch a PVP que game i get the message "Platform Error" and it does not allow me to join PVP que. I believe it happens if i have just recently ended a custom game as well. The problem error does seem unique to any 1 pvp que either. Further, it will happen over and over until i relaunch the client. Alternatively i have figured out that if i go back into custom games, create a game then exit my game room upon creation i can then launch a que game in PVP. Wierd i know. Not sure how i figured out that last trick, just have a knack/patience for figuring out stuff like that. Cheers m8s. Ugly
