I have some issues with the windows client (similar to what other people have noticed).

I managed to ran it as Baritus advised by disconnecting my wifi. Then I tried adding nodes that I took from various places in this thread via the console addnode "IP" "add". However when I activated the wifi again, the software eventually crashed again and upon start-up all nodes I added via "addnode" console command disappeared. Is there any way to sync with DGC3.0 software?

Alternatively I got an old version (1.1) which doesn't crash upon startup when wifi is active but it doesn't have the "addnode" command available and therefore I can't sync either.

Any ideas how to sync successfully with either version?
