Can't change frame when its URL changed

HI there,
I use Telerik in web automation testing. In the newest version of web service, some frame's name was changed and I couldn't use all element in those frames. I tried to change the BaseUrl of Frame but when I closed Project and opened again, the frame was roll backed to original. Please take a look in my attachment:
Frame Main in MainpacEAM : http://localhost/Mainpac2011/DashboardTransfer.aspx. I need to change it to :http://localhost/Mainpac2011/Dashboard.aspx.
Please give me some advise. Thank,
