A Gundam Evolution Error Code 0x09030302 (175) occurs when the game thinks you are still in a game. Part of protecting against in-game dropouts is that you can’t join a new game until the one you were in has ended. Unfortunately, a bug makes the game think you’re permanently locked into a game, making it impossible to queue. Fortunately, there is a solution for this.
How to Fix Error Code 0x09030302 (175) in Gundam Evolution
One of the penalties for leaving a game in Gundam Evolution is that you have to wait for it to end because you can join a new one. Unfortunately, this penalty can befall those who do not intentionally disconnect. In this case you will get an error code 0x09030302 (175) and the game will kick you out of the queue. To make matters worse, a bug is currently causing some players to get stuck with this error code indefinitely.
However, there seems to be a solution to this error. If you join and leave a practice match, you should be able to queue back up as normal. This doesn’t seem to work for everyone, but many players report that this was their solution. If it doesn’t work the first time, just keep trying and hopefully the problem will be solved easily since the game has just come out.
