So you're sending 0.005 to 1CXth4bzYYwPbLCv3Dxpyj9HbNsekni1V9, is that right?
Got that address from the raw transaction and I can't find the transaction in any block explorer. I think it is indeed a network problem. Try verifying the network from Tools > Verify network and make sure that you have a green light at the bottom right of the client.
hmm.. that's weird, because my peer count is a 10 and I just now verified it. I'm still confused about what it's saying about "Waiting for feedback about this transaction from the bitcoin network".. how long will something like this take since the tx id isn't showing up in blockexplorer?
Usually it shows up in seconds for transaction with high enough fee, and yours have high enough fee. I'm not sure what went wrong but I pushed it to
https://blockchain.info/pushtx manually, so it should show up in block explorers now.
Edit:
In case this happens again, just take the raw transaction and push it to network using the link above. The raw tx is that long thing above size that begins with 010000000.
