So sorry guys, lot of work here.
I promise I will try to answer all your questions today, when as soon as I have 15-30 minutes free.
For now, I uploaded a new revision of wallet. You can download it here:

This revision fixes the "Connection errors" and gets around a 5-10%+ hashrate.
Regards!
I dont know if it really worth to go public if development is on so early stage. There are all kind of problems typical to young coins. Of course it facilitates development, but people may lose confidence in an overall success.
