Guiminer and Litecoin

[Variant65]

Posting here because still cant post in relevant place.

 I have finally managed to get guiminer going but am not seeing my hashrate (currently 160kh/s but will quadruple that if I can get it working right) registering inside Coinotron. Also I am getting only stale/invalid shares (about 1 every 2-3 seconds) on the local app, the accepted amount stays at zero. I am using stratum through port 3333. Any suggestions?

Thanks
