Strange error when try to include piping files

Hi to all,

when i try to include more than one piping file into the Caesar 5.20.3 built 100715, the program show me this error!!

I try to reinstall the Caesar, but nothing!!!

Thanks

Check that both jobs to be included are:

a) 5.20 files (and not from a previous version - if so resave and Error Check them)

b) use the same units system as the main job

c) if the job files to be included are "c 2" archives, make sure the "read only" attribute flag is NOT set.

If you can't figure this out, send the files in to Tech Support.

Thanks Mr. Ay

unfortunately the problem is only on my computer because my colleagues not have the same problem with my files!!

All jobs are makes with 5.2 Caesar, the caesar.cfg is the same for all the files and the "read only" attribute flag is not set.

Thank for the interest.
