Lost my progress!!

Unfortunately, we can only suggest similar advice.
You could try the uninstall/reboot/reinstall a couple times.
Some people have success with fixing their issue with a second or third reinstall cycle. Just Do Not Play until all downloads are done!
Otherwise,
I would call EA and ask for a rollback to before the issue started.
You will lose any progress or items event and regular play that you have gained since the problem started. So you will have to make the judgement if it is worth it or not.
Unfortunately it is now the weekend and US help is closed.

Here are some tips for contacting EA.
1. Try to get a call or, if you have no choice, a live chat, between 9am and 5pm Central time Monday-Friday in the US.
2. Explain your problem and all the steps you have already done.
3. Be polite but firm that only EA can fix your problem.
4. If you have bought donuts, tell them how much money you have spent in the game.
5. If the csr refuses to help you, just hang up.
6. Request another ticket and call back.
7. Repeat until you get someone who can help you.
8. You will have to be persistent. First level support outside the US really can't help you with this type of problem. You need someone in the US or possibly Ireland, to fix your game.
9. Good luck.
