Hi Baldev,
You have two or more versions of Numbers on your Mac—Numbers '09 and Numbers 5.x.x.
The files you are trying to open were last saved from Numbers 5, and you are attempting to open them with Numbers '09.
Numbers '09 files contain (and need) an index.xml file. The newer version(s) have a different file structure which does not include (or need) this type of included file.
Solution: Quit Numbers '09 (Numbers (menu) > Quit). Launch Numbers 5.x.x. Go File > Open (or File >Open Recent) and open the files that have been giving you trouble.
Regards,
Barry
Added note: Numbers '09 and Numbers 5 can co-exist on the same computer. This is also true for the '09 versions and more current versions of Pages and Keynote. The newer versions can be found in the Applications folder. The '09 versions will be in a folder named iWork '09, which is also in your Applications folder.
Although Numbers 5 (and now 6) has gained several new features since its introduction, there are still things (eg.mail merge) doable in '09 that have not yet been written into 5 and 6.
The case for keeping Pages '09 around is even stronger in terms of capability, as you may have noticed if you've read much in the Pages for mac community.
