Ok ... now everything works perfectly. Thanks you all for your help. Problem was solved but if you want continue with discussion about recommended fees. Maybe it helps to others who read it.
Yep you are right. I didn't know that having a lot of 'dust' in your wallet would bite you in the ass, after reading this thread I know. Also, one another reason to not use faucets.
In my wallet transaction fee is set to 0.00000000 and I never pay it, yet transactions are processed - fast and without problems, is that normally possible? Maybe my wallet is taking fee stealthily?
