Unfortunately we are having hardware problems with one of our database servers at the moment that is dramatically effecting the speed of PokerStars searches. So to keep as much functionality up and running as possible we have temporarily disabled some features, such as searching on the old site and using the HUD with PokerStars until we can get the problem solved.
We’re very sorry for the inconvenience caused and please be sure that we working flat out to get this resolved.
