Oh thank god I'm not the only person who has experienced this!! I made a post the other day, but it seemed to have gotten lost in the forums.
Copied from my other thread:
I don't know what happened, or what was changed with the last patch (notes would be NICE Cryptic..) but ever since then, when I try to interact with a Ferengi merchant, my game freezes, the sound/music begins to loop, and I have to crash out the game to get it to close. More then once this has caused a complete hard lock of my computer where I had to hold in the power button in order to reboot.
I talk to the merchant, press 'Continue', and as soon as it attempts to load the inventory, this is when the hang happens- The prices load, but no items. I've never had ANY technical issues like this when playing before; the game has been amazingly stable for me (other then random server lag/disconnects, but that's normal for a new game).
