Motorola Motocast :: Error When Accessing Mymotocast.com?

I've installed motocast on my pc and it works great connecting to my Droid RAZR. But when I go to mymotocast.com using a browser on my pc, as it loads the music I get an error.In Chrome the error is "An error has occured which prevents the application from running: cannot call method 'get' of undefined." In Firefox the error is "An error has occured which prevents the application from running: c: is undefined."In Internet Explorer the error is ""An error has occured which prevents the application from running: unable to get the value of the property 'get': object is null or undefined."It's only with the music (although I can see my songs behind the error message). The tabs for Video and Files work fine - in fact, using the Files tab I'm able to get to my music. None of these files are on a C drive, btw.They are all in Windows 7 Libraries for "Documents" "Music" and "Videos" but the actual files are on a D drive. I suspect there is something in the code for the Music tab that's having difficulty with that but obviously I don't know.
