What is going on with E-Newsletter?

Ok this happened again. Not sure why but E-newsletter 2.3 was working perfectly fine and then again when I have an newsletter that had to be delivered I get an error cannot connect to smtp server. i didn't change any settings and used the same computer etc... I've been ill so haven't been on here lately. In fact cole was unable to figure out last time. I installed an older version and that took care of the issue. Now not only does the older version not work. I accidentally upgraded to the newer version (really didn't want to do this) by selecting to upgrade all of the WPMU stuff from the dashboard. Now my custom themes are gone as well as the new version doesn't even show all of the templates that came with the plugin!

New layout is totally confusing and now I know why a couple of my clients went back to godaddy and their easy page designer...
