I've added 2 email accounts and been successfully using them for a few days now, so went to add a 3rd and get the same error message above, but with no code after it (so: zclient.IO_ERROR: unable to parse response

- it stops at the colon.
My issue is that now I can't access anything! When I open the Zimbra Desktop icon, it just returns to that same screen with same error message and I can't get into my other 2 accounts for email or contact data.
What do I do?
NEVER MIND - I'M AN IDIOT - USER ERROR! I was selecting Zimbra account instead of POP. (And after I spent 1/2 hour searching through old postings to make sure the solution wasn't in front of me. In the words of Homer Simpson, "Doh!")
