Help!: Script error

everytime i try to open an existing route, I get a popup error saying that there is a script on the site that is causing the page to load slowly.  If I choose Yes to stop the script from running, the route eventually opens but looks incorrect.

 I am running 7.0.6 of IE.  It appears I do not get the same error in Firefox.

is an example

 

Before the website was updated, I was able to download crs.files to my Garmin Edge 205. Now when I go to save as Garmin file, nothing happens.  I switched to Firefox and still not able to save as a Garmin file.

I'm having the same problem.  It's rendered the website useless for me.
