Did you follow the security guidelines to only download electrum from
https://electrum.org and to verify its signature as stated on the website ?
Verifying the signature is the only way to be sure you have the original (non-malicious) version of electrum. This is a mandatory step.
You say your BTC's haven't been delivered. Did they 'leave' your wallet ?
If you look at the history-tab, what do you see ? Do you see an outgoing transaction ? If so, does it have the correct details (e.g. output address) ?
If the transaction details are correct, head over to a block explorer (e.g.
https://live.blockcypher.com) and enter the transaction ID, then check whether it is confirmed.
If the TX details are not correct (i.e. not what you have entered), your computer is somehow infected with malware (either malicious electrum or some other kind of malware).
