The "technical support" section would probably be more appropriate in this case but...
First off, the coins are not lost, just in limbo for now.
Typically if you are now connected to the internet, and your synced - that is your block source is up to date - then your wallet should periodically rebroadcast your transaction to the network, and then it will get confirmed.
But some more info would be useful to troubleshoot your issue, what wallet software and version are you using?
