Market App crashes on Samsung Galaxy Ace

i have samsung galaxy ace, yesterday i rooted my phone and installed the link2sd application, everything was fine, today when i tried to install an application using market, the market just crashes while opening, i uninstall the app, and got the new apk from internet and install that, same happening with that, after i read a review on internet, that if the market app crashes, just clear the data from settings, i did the same, it was working fine, but when i clicked on Accept and Download button to install the app, the market again start crashing, do anyone have any idea why is this happening, is it because i rooted the phone and partitioned the SDCard and installed the Link2SD application yesterday, did anyone have faced this issue.
