Not working on windows 8.1 Rated 1 out of 5 stars

I tried reseting my nightly and installing the addon again but the error is still there.. When I press the enter, Nightly won't do anything. The error was fixed when I disabled the addon... Please fix this as this is my favorite addon.

This review is for a previous version of the add-on (0.7.1.1-signed.1-signed).  This user has 2 previous reviews of this add-on.

Version 0.8.0 should fix that.
