Hi, and welcome to the forums.
Since you haven't done a backup in 5 months, you might as well just start over.
Connect via Ethernet if at all possible.
To delete everything on the Time Capsule's internal HD, use +*Airport Utility.+* Select your Time Capsule, then +*Manual Set-Up,+* then Disks in the tool Bar, then the Disks tab below it, then Erase. The "Quick Erase" option will only take a moment.
Then re-select your Time Capsule as the destination, via +Time Machine Preferences,+ and let it do a full backup; that will take quite a while, even via Ethernet..
If there's a problem, don't just ignore it. See [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum); and/or [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum); and/or post here for help.
Also, remove the check from the +Warn when old backups are deleted+ box in +Time Machine Preferences > Options.+ When the Time Capsule gets full, Time Machine should then delete your oldest backup(s) to make room for a new one.
