Pokerstars, rigged too?

[Offsuit27]

I was playing in the poker tournament in Pokerstars special freeroll.
At the start of the game i got lucky.
Someone went all in (45000) and I've had a strong with 938500+) hand so i called. I won but after playing for two hours i never win any hand anymore.
Do you think, pokerstars is rigged too?
