I am trying to upgrade from 0.8.0 to 0.8.2. I un-install 0.8.0 and I get a success indicator. Then I have tried to install 0.8.2 from my computer and I get a upload error. I also have tried to upload it to the server as a zip file and point to it as a URL. Then it goes back to the admin screen but it is blank and it is not installed. If I reinstall 0.8.0 everything works perfectly. I really want the sub menu feature of 0.8.2. What can I try next?
