I have same problem again but ...

I deleted old version of qt.
Download new one 1.0.0.1-unk-beta

It was everything allright and suddenly desynchronization.
So ok. I deleted all blockchain and all files (without wallet.dat and flappycoin.conf)
and I ran Qt again.
And this is what I saw after relaunch....


Anyone know what should I do to make it synchronizing?
