PSO2: Tweaker Not Launching Game

Hi guys,

I've been trying to get onto PSO2 for a few days now and have had nothing but issues.

When I click the launch button nothing happens, the tweaker icon on the desktop goes away and i need to click the "im done playing PSO2" button in the running tasks to get it to come back.

if someone could help me get online tonight I would be much obliged.

Now it's actually running but as soon as it starts to load up a windows pop up comes along saying "PSO2.exe has stopped working"
