RSS feed URL?

hi there,

i was wondering if someone can tell me what the RSS feed URL is for this blog: http://imaginationmedia.info/blog-feed/

i have the RSS feed file as this: http://imaginationmedia.info/?feed=rss and i have tried every other combination that i can find with no luck. the feed reader seems to work on my computer but not when i upload it to the server, it says it can’t read the file. when i use a different blog URL, the code seems to work on the server. every time i google a solution, i’m given a different string. help!

thanks,
densie
