Miner can't pick up/accept any shares

[RunarVM]

Hey guys

I've been googling all day to find a solution for this kind of issue, and no luck.
I try to mine ultracoin (tried to mine yacoin too) but my minerd cant accept any shares because of 'Low Difficulty'.

Like this:

A friend of mine told me to change the difficulty at the pool's website.
But it seem like i cannot change it...

Pool uses Vardiff, which automaticaly sets the suitable diff for your miner.

It looks like your settings aren't correct (i.e. wrong algo, mining software). If you could share your command line, it would be helpful.
