problems with directRT input file (case 17696)

[shimrit]

Hi,
After running an input file for a year or so, we suddenly experience a problem.
The error is : This does not appear to be a directRT input file.
When I look at the input file, it seems that some path names are with upper case letters and some with lower case.
Wasn't sure this was similar before the error appeared.
Didn't find any other reason.
Any suggestions?
Thanks,
Shimrit
