E-Newsletter V3.2.1 can't make work

For starters the auto update plugin recognised that E-Nwesletter on my site was out of date. I tried to fix it through the automatic update function, and this failed. I then phyically dowloaded the folderf rom your site but it is a .rar file. This was not liked by my site when i tried to upload it. I then converted it to a .zip file and had the same problem. Please help. The reason I am trying to update is the plugin will not allow be to send a newsletter from my ipad. I can't choose a template either. When i get to save and send it just hangs there. Hoping you can help.
