unable to import .ris file from web

I want to use the direct export citation option from nature cell biology. I get the message

“C:\Users\XX\AppData\Local\Temp\ncb2000-1.ris was not opened because there is no associated application. Change the association in your settings.” (approximated translation, the message I get is in french).

If I open this file from endnote X4 its OK.

I tried to change the association in FireFox, in the control panel (I’m running win 7 64 bits) but no way. What should I do ?

Thanks for advice.

No idea anyone ?

I think that I associated the ris format to endnote directly and not to theresearch soft direct export program. Now it works. Thanks for your help.
