Fixing that now excuse the hiccup!

Please check GitHub for the patch 3 done to v0.8.4.2, you should no longer have issues compiling on Linux

We just corrected this. Please re-download your source from GitHub and try again.

Wow I hope you are not on your own chain , it would be to wasteful

Be sure that you didn't mix up your ESP1 and ESP2 addresses. MANY people have been doing that lately.

There is an old chain and a new chain. No forks.

0 active connections to the network since the last update of the wallet. node list does not help.?

Node list is wrong. Doesn't use it!

I think you use different espers folders.

v1 meanEspers, v2 meanESP in your roaming folder.

So many people having probs. Think there needs to be an old esp1 wallet & new esp2 wallet added to top of the op, too many people are sending esp1 to esp2 addy and vice versa.
