Can’t create a new community?

This is my only account, and I only have one other community created (/dogs, please join if you’re a fan).

I DID have a second community created a week and a half ago but Digg admin removed it per my own request. I have an “open slot” to create a new community, but the app is telling me there’s an error and I can’t. Can I please have some insight to this issue? Thanks in advance!
