In the dimecoin.conf - may need to update the seeds.

addnode=115.28.16.229
addnode=109.65.166.87
addnode=99.99.203.102
addnode=86.184.213.156
addnode=115.28.11.226
addnode=77.47.170.101
addnode=37.146.68.21
addnode=37.146.68.215

I have 172 peers connected in total - and over half these seeds are still working.

Did update to the 1.2 client from dimecoin.org?   Did recompile from the latest GIT?
