why no connection on my windows wallet ??

Go to %appdata% go into the procom folder , create a file called procom.conf and write in it:
rpcuser=something
rpcpassword=more_something
rpcallowip=127.0.0.1
listen=1
server=1
addnode=seednode1.procomcoin.org
addnode=seednode2.procomcoin.org
addnode=seednode3.procomcoin.org
addnode=seednode4.procomcoin.org
save the file and restart the wallet now it should sync
that's it.
