Do you have an antivirus?
Some AV will block Electrum because of a known false-positive virus detection.
If that's the case, temporarily tun off your AV and/or make an exception for Electrum to your Firewall and AV.
Regarding the receiving address, it will always display a new address in every transaction you make.
Try displaying the addresses tab (
Click "View"->"Show Addresses") and check if the first used address is there.
Also, if it stays like this forever, do you guys think if I called coinbase, that I could cancel the transaction so I don't lose so much money? So then I could learn to use a different program similar to it?
There's no way for you or them to cancel a "
confirmed" transaction, Bitcoin's transactions are irreversible.
You haven't lost any money as long as you haven't screwed-up with the backup (
the 12-word SEED phrase) or downloaded a fake Electrum wallet.
All you need to do is to restore that SEED to any Electrum wallet installed to other machine/mobile if your PC was the cause of the synchronization issue.
Lastly, check on an
online blockexplorer if the address(es) in the address tab have a balance by copy-pasting each address to the search box.
