Hey Linh,
Sorry to hear that, it's really hard to be starting again from scratch. And I can imagine that for now the wait seems endless... good luck with putting together again your application, and definitely use the new form, you don't want to delay more, and get the package sent back.
The "good point" is that it should be fairly simple to put it together again, and so you should be able to send it soon ( with maybe new criminal records, as they might have expired?).
Hopefully the time for sponsorship approval will start to go down again and you won't have to wait 90 days again, but of course - that's wishful thinking for the moment. The pace seems to have picked up a bit for now, as some march applicants have received their approval in 85 days. I know it's a very meager consolation for now, but don't give up, you can do it! waiting is really hard, but it is worth it in the long run.
Good luck,
Sweden
