ELGG in XAMPP Problem

Ive installed ELGG 1.6.1 in XAMPP lite(latest version), ive installed it correctly, im loging as admin, disabled email validation, i tried to register for another account to test some plugins. The registration was successful, but for some reason, i cant login. Once i click login, nothing happen, as if the page is just refreshed. I tried other browsers as i think its a cache error, but still, the same, cant login.
