I think I had the same problem and sent a note to the webmaster at that
site, they sent me this note back, I tried everything and it worked.

" Thank you for your interest in hmaservice.com. The WebTech service
information area has been working properly. Please check the Site
Requirements page to confirm that you are on a compatible operating
system and browser. Additionally, there are some security settings in
Internet Explorer that can be set to block scripts necessary for
WebTech operation - we recommend the default settings for your browser,
or check under security that ActiveX Controls are enabled. If using
internet access through a network, or with a personal/client firewall,
some firewall settings will not permit scripts that are necessary for
WebTech, and you or your network administrator may need to check
firewall permissions.
  For specific pages or graphics that do not display, be sure that you
have the required Adobe plug-ins installed (the Site Requirements page
provides links to the Adobe site where these plug-ins can be downloaded
at no cost).
  Specifically, the triangular symbols you described are the indicator
for an SVG format graphic, when the Adobe SVG Viewer plug-in is not
installed. This plug-in is available, at no cost, from the link on the
Site Requirements page.
  I hope that these suggestions assist you in locating your
access/display error and allowing you to use hmaservice.com. Feel free
to contact us if you have any further problems.
