Ground bugged?

Since yesterday when i uninstalled by mistake the client , whenever i try to run i got my pg bugged...getting stucked on ground and stepping back...strange since it never happened before...it's a bug for all or just my toon which is lazy to run...? :|



I click on a far spot , and instead of making the whole path my toon get stucked after 2-3 steps...or don't move at all...heh...
