Linksys Wireless Router :: E4200v2 Cannot Create Storage Share

Just bought router and installed.  I cannot create share in Storage settings in Advanced settings.  I hit Create Share and it brings up the dialog box where I enter the display name.  Share entire partition is checked already.  I save settings and I see the box going to the form where you assign the Group roles, but then the box disappears and closes.  All I see is the original Storage setting page with the Create Share button still there.I tried this on Win 7 using both IE8 and Chrome browsers.
