dont know how to tell what tribe was deleted

You should try using your Windows search function and type the following in the file name field (exactly as shown): isola2*.ldw

If you copy the list of files (along with the dates of the files) that it finds, I can tell you which file(s) are missing.

im not understanding lady CFII

im still very confused how to find lost tribe

As Barbara said, If you don't know how to search in Windows, is there a friend or relative who would be able to help you?

Alternatively, there are a lot of good Windows learning sites on the 'net. I googled "Windows tutorial" and found lots of free tutorials on basic Windows tasks. Maybe that would help, Ivory Rose?
