Autodesk Seek

[#1]

I upgraded to Revit Structure 2011, and now I can't open items I have downloaded from Autodesk Seek. I get a message that it can't find the program to open them with. I never had this issue on 2010, any thoughts as to what program I need to use to open them with?

Thanks!

I realized that 2011 uses .rvt files not .rfa files. I had to reload 2010 to be able to open .rfa files, which were then converted to .rvt files.
