Content Encoding Error when installing vBShout

[pjclas]

I apologize if this is a duplicate thread, but I've looked through many other threads regarding Content Encoding Errors and none of them seem to help me.

A little background first. I just recently upgraded my forums to vB5 5.1.1. I completely erased the prior 4.1 forums directory and extracted the vB5 package, then ran the upgrade tool to migrate the database. Prior to this I deleted all the vBulletin third party products I had installed.

After getting nginx configured to work properly, I downloaded vBShout (vB5) v6.1.0a8 [Lite] and extracted the content of the uploads folder to my forum directory. I then went in to Hooks and Product and clicked Add/Import Product, then put

./packages/dbtechvbshout/xml/product_dbtechvbshout.xml

into the "import XML from your server" line. When I clicked the import button I got the following:

Hooks & Products System
Importing Product, Please Wait...

After that the screen was replaced by an error message:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

When I look at the product page again, it appears to be installed, but I have no idea if it is installed correctly. I do not have gzip compression enabled in the forums so I'm not sure what else to look at.

Oh, and as an FYI, I tried this is IE, chrome, and firefox with similar results. Only difference was that the progress bar animation only works in IE for me. Any help would be greatly appreciated. I can easily repro this if there is a way to gather more information.
