Electrum 2.0.4

Tried to send a couple times but it gave me some "network doesn't support transactions" error. So I switched the network to some random one (h.1209k.com)
Now it went thru and says "pending" . . . but when I check blockchain "Transaction not found"  is this common? Whats up? It's been like 10 hours no change

***Thanks to all who helped me. I downloaded the new version and it went through
