I am using PSO2 Tweaker.

The subject line is the error I keep receiving when trying to run the pso2 tweaker. I have ver. 2.6.6.0 and when i try to update it , i get told I need to update to 2.6.6.9 (i think that's right). I click yes, it says "Downloading update..." in the dialogue box and then immediately says "ERROR - the specified executable is not a valid application for this OS platform." Then the PSO2 tweaker freezes and I cannot click the orb or do anything except close it using my task manager.

I have Windows 7 and a laptop that's only a year old (Samsung).

Up until a few hours ago, everything was working perfectly. In fact, I ran an EQ earlier today around 1030AM EST. I'm not sure what happened between now and then. Any help would be greatly appreciated!
