What kind of notifications do you see in your wallet, when you're trying to send Waves? Please show me a screenshot. Also, which version the wallet are you using?
Very strange. How long do you wait after sending? By the way, click on the backup (top right corner) button and look, do you see the same waves addresses? Please don't show this window to someone!
Your waves address http://wavesexplorer.com/address/3PJmvnAAvYDkggwgGZ8yyPzeUGTSZQuHia1
Try to use a different Internet connection or try to temporarily turn off the firewall. Also. you can try using a different browser. If are you using Google app, try to run the index file from the folder WavesGUI-0.3.3.MAIN that you can download here - https://github.com/wavesplatform/WavesGUI/archive/v0.3.3.MAIN.zip
Unzip files. open folder. find the index.html file. open with a different browser (eg Firefox). import your seed. see user's manual -
