There's no problem, that's what the network difficulty is. Per your screen shot you are hashing to difficulty 32, pool difficulty, every hash you hash that results in a solution with difficulty greater than 32 should be accepted. You're using a way out dated version of cgminer. 4.9.1 is current, try a new version maybe?
I downloaded the version you said, but when I double click on start-BTC it disapear quickly I tried the "--scrypt" thing it didn't work so I clicked on cgminer directly now I have a cmd window with "Stratum from pool 0 detected new block", is that normal even my dashboard on the pool websites isn't showing anything?
Scrypt support was removed from the official cgminer so you won't get any help for it in this thread.
