I'm having the same problem.  I tried to send the contents of my wallet to another wallet, and the transaction was greyed out and said, "This payment has not been transmitted yet."  I looked online and found this post.  I'm not at all tech savvy, but I tried to follow the instructions as best I could.  I selected Report Issue, but I don't have email enabled on my phone, so I tried to Bluetooth the report to my computer and send it from there.  That didn't work, as my phone says "Bluetooth share: Sent files, 0 successful, 6 unsuccessful."

Thinking that I could probably resend later, and that I probably had a copy of the report on my phone, and being in something of a hurry, I went ahead and tried the next step, Reset Blockchain.  That was last night.  As of midday today, my wallet shows a balance of BTC 0.00, and says, "No Bitcoins received so far."

Are these bitcoins lost forever?
