I had same problems with DLink 624's. Had to quite playing on PokerStars (and a couple of other sites).

Took three of them back and ended up using a DLinK 524.

The 524 has worked for over a year now with no problem.

Does your 524 feel abnormally hot? If it does there may be something physically wrong and it needs replacing. I think there were a whole bunch of 624's and maybe some 524's that were faulty. They would get hot and then not work properly
