@ChainLis i tried the tweaker after i installed the external launcher. tewaker wants the pso2_bin which i just created in the very same folder like tweaker was and it worked this far but then it wont work without this shit of store connection >.<
Don't install the game into the Tweaker folder. it should be on your C drive. When installed on the C drive it should be like C:\PHANTASYSTARONLINE2 <=this is the folder it will create when installing.
