Hi, noticed some problems with the RSS and XML/XSL modules in medium trust?

I am trying to access RSS feeds and XML files from other websites, but I get error in the modules. How do I get around this? My ISP is running medium trust.

RSS error:

Could Not Connect To http://api.flickr.com/services/feeds/photos_public.gne?id=43695459@N00&tags=2005dmh1&format=rss_200. You Should Verify The Source Address Is Valid And That Your Hosting Provider Has Configured Their Proxy Server Settings Correctly.

XML error:

Error: XML/XSL is currently unavailable.

I have seen other people posting same problem, but I cannot trace a solution. Could someone please help?

kind regards,
