AutoSoulWars Pro, Flashing Screen?

About 5 min ago I started my SW Pro bot form Rsbots.net. I used the non-hd, fast version, not for multiple accounts. When it loaded and the boxes that show how long you've played for, amount of zeal etc appeared, the client started flashing. I could always see it, but for a split second it would flash like a light. The whole screen flashed, but nothing else. Does anyone know what this could be from? When I tried the version for multiple accounts, it did not do this.

Help please?

Edit: The signed version isn't working properly at all.. .Just got kicked out of a game for not doing anything... Un-signed seems to be working.

 

I would, but I couldn't choose the correct world. I always logged into a f2p world even if I choose the member option. Once entering my account info, I logged directly into a world.
