Yoo,
Chill out man hehe.
First of all. The cards that come are never fixed. Every pokersoftware works with a random number generator. Besides.. If it was true, then pokersites would've been shut down long time ago

these things happen both online and live. Downswings are always gonna happen and it's up to u on how to deal with that.
But you are right on 1 thing. PKR is not that great of a site. Blind structures are redicilous and the support can be slow at times (that's because their staff is not that big). Cashing out can take several weeks! Abnormal!
I have cashed out on a certain time and instead of withdrawing to my bankaccount, they sent it to my moneybookers. ??? wtf ???
Weird site. But still fun if you look for realism haha
Just relax and have a beer.
Wish u good luck in future poker.
