Yeah the wallet doesn't have any hardcoded seed nodes.   You need to enter some manually to get it connecting.   Try going to the debug console from the wallet menus and type the following:

addnode node.cryptocronic.com add

You can also create a tradecoin.conf text file in C:\Users\\AppData\Roaming\tradecoin\  and put a list of nodes like:
addnode=node.cryptocronic.com
addnode=104.251.218.157:12499
addnode=185.188.6.8:12499
addnode=198.12.70.154:12499
addnode=45.33.42.71:12499
addnode=45.79.201.204:12499
addnode=51.15.164.53:12499
addnode=66.228.57.25:12499
addnode=78.179.130.1:12499
addnode=83.169.7.202:12499
addnode=84.29.56.160:12499

Hope that helps.
