MailPoet just not performing

I have been using Mail Poet for some time and have been happy…

ALL of a sudden – nothing seems to work, even though I have upgraded.

I am not able to find the answers on the forum where directed for help… I have a campaign that is going to fall short of a deadline if I can’t get this managed.

1. When someone registers – they are not receiving the confirmation email so nothing is getting subscribed status to even receive future emails.

2. When I create a newsletter, I am having to reduce the size of my screen to about 25% to be able to get up to the formatting-edit tools, at which point it is barely visible for reviewing and at times kicks me out of the edit screen before all the work I do can be saved.

3. When I DO finally get to the point of sending a preview – that doesn’t go.

I have checked with my host and all the email information is set up correctly – per my domain name not gmail or something else. I have checked and both PHP and sendmail tests worked.

I am NOW totally beside myself and ready to chuck the whole product and go back to Constant Contact…. 🙁

Help Please!
