Why am I getting this error: 0x8800CCCD2 with Windows Live Mail 2011 on my 8.1 PC?

Why am I getting this error: 0x8800CCCD2 with Windows Live Mail 2011 on my 8.1 PC?

Also Why is the program going through all my folders WITHIN each email account to download emails?  

The error also states that one my accounts does not exist, but it does!

Another problem: I'm finding emails for one account listed in the wrong email account!  

The reason I downloaded 2011 for my 8.1 is that 2012 would NOT do groups.  If you have a resolution for groups in the 2012 edition, I'd like to hear it.  

I'm wondering if the 2011 is not working well because I have 8.1, but I absolutely need groups.

Thanks,

Terri
