Download problem Rated 4 out of 5 stars

I have a problem with downloading SpellBound. My Firefox says that the file is probably damaged. Could the developer check and fix the problem?

This review is for a previous version of the add-on (3.0.5). 

Read the entire EULA before you download this!

You may not be able to install this addon with Firefox if you do not have "Accept third-party cookies" enabled, unless you add a cookie allow exception for "mozilla.org". You can find the window to add "mozilla.org" to the cookie allow exception list, by clicking on the "Exceptions..." button located under the "Privacy" section of the "Options" window. Enter "mozilla.org" in the "Address of web site:" field, then click the "Allow" button and "mozilla.org" should be in the list. This requirement has to do with the way all Mozilla experimental addons are downloaded and has nothing to do with this addon.
