ActiveRecord Security Exception - RESOLVED

[SarcasticBaldGuy]

Wanted to post this in case it can help others later.

I downloaded Castle ActiveRecord 2.0 last night and proceeded to
update an application using an earlier version. When I attempted to
load the configuration from the web.config, I received the security
exception listed below.

Google led me to believe it was a "Medium Trust" issue which didn't
really help since I'm running locally.

After beating my head against the desk, I started to copy the files to
a USB drive to try on another computer and windows alerted me that the
files contained additional information that would be removed.

Sure enough, checking the properties of the Castle files resulted in
the "this file came from another computer and might be blocked to help
protect this computer" message being displayed and the "Unblock"
button being visible.

Once I "unblocked" all of the files (all at once using Streams v1.56),
everything worked just as it should.

I didn't see this particular situation or solution mentioned anywhere
on the internet. Hopefully it will help someone in the future.

Here is the exception I received:
