Open AI files in Inkscape?

[mahesh]

Hi, I'm having problems opening Adobe Illustrator files (.ai) in Inkscape. I can save them perfecty fine, but for some reason, Inkscape says that it "failed to open" the file. I tried Xara Xtreme and it said that I needed to install imagemagick. I installed imagemagick from the source and now Xara will still not open them and when Inkscape attempts to, it hogs up all my memory so that I have to restart my computer. I get the same result when trying to open the very same ai files saved by Inkscape. Do I need some external libraries or something?
