since u r using VSS .. i think the problem is that u're not getting the
correct files .. as soon as some one checks out the project and adds a new
file .. he has to check in the project file along with the new file. then he
can chk out the new file again .. and then when u do get latest of ur
project .. all the correct files will be there in ur system ..
even we had faced some similar issues ..
pls chk if this kind of approach solves ur problem ..
i hope it helps ..
