Time Capsule backups disappeared

Hello!

I would like to know if anyone has experienced the problem I'm having now.

I have a 2TB Time Capsule to backup the data from my MacBook Pro (2.53GHz Core 2 Duo). A couple of days ago, I needed to look for a backed up file, so I ran to my TC backups, but they were all gone. I have absolutely no idea what happened. The error message was that the backup disk could not be found. I don't think the data was erased, because the space available in the TC is the same as before, but I just can't find anything there. When I enter Time Machine, all it shows is the Today (Now) backup. I tried to select the backup disk again and click the "Backup Now" option, but all it did was a new backup with all the data in my computer (as if it was my 1st backup), so I am 200GB short now.

I really need some files I had in those old backups... does anyone know where I can find the old backups through Finder? Any idea if my files are still in TC??

Thank you for the help.
