Installer Hanging at Add-Ons

I had a previous version of EasyDiscuss and today, renewed my subscription. Upon doing so, I attempted to upgrade. The upgrade of the system went as it should, however, when it comes to Step 4 of adding the add-ons, the system hangs at 0%. I next downloaded the newest version installer from the website and attempted again with the same result. Unfortunately, this has locked the forum as it now just goes to the installer instead of the forum. How can I get past the add-on step of the install process as it's just hanging there.
