When I try to import an editor profile, I am now getting:

Error
ERROR_XML_LOAD

XML: Start tag expected, '<' not found
I am using JCE 2.5.2 and I've updated all the plugins to the most up-to-date versions. I'm only using JCE plugins, no 3rd party tools. Any idea why this might be happening? Thanks.
It seems that module parameters haven't been configured properly. Please make sure that you are using a valid twitter username, and that you have inserted the correct keys. Detailed instructions are written in the module settings page.
