I was invited to join a team, but I want to get my individual account back.

Your team admin must have transferred your files to another account when they first removed you from the team then Isuru W 

Can you check with them if they can find them anywhere to re-share them with you?

Is this something my subscription is not there anymore?

It's expected that your subscription is no longer active. When you joined the team you would have received a prorated refund for the time remaining on your account. When you leave a team you'll be back on a Basic account. You can resubscribe if/when needed.

I have forwarded this message to them. Not sure how they did. But said they have followed the instructions from the given link.

Yes, Rich​ when they added me to their DB team, I was refunded. Just curious if I pay, can I get my files back as Admin says he did, according to the link.

Paying has nothing to do with your files. Your team admin is the only one that can potentially recover your files for you.

When you were first removed from the team, the admin had the option to transfer your files to another account. If they did that, then that person may be able to share them back to you.

Thank you, Rich​  I have already asked them to re-add me to their DB team and follow the steps in the video to leave me as an individual account. I will update you as soon as they respond. 

Hi, Rich​  the Admin has invited me to join their DB team again, and I have accepted. Now that all files are there, is there any way I can leave the team with my files without losing any of them, without involving an admin person? Seems he and I can only access my files. 

Hi from me as well, Isuru W.

If you'd like to be removed from the team and return to an individual Dropbox account, only the admin has the ability to do that for you.

They'll need to remove you by following the steps in this article.

This will remove you from the team, but you'll keep your account and your personal files. In the article I linked, you'll see exactly what data will be transferred to the individual account and what won't be transferred.

I hope this helps!
