9.7 Unit 50 Error

Unit 50 is the restart file. If the path or file name in the file is incorrect, or the restart file does not exist in the /rest directory below the executable directory, the model will stop with this message:

8:1525-014 The I/O operation on unit 50 cannot be completed because an errno value
           of 2 (A file or directory in the path name does not exist.) was received
           while opening the file.  The program will stop.

Verify that the path and file name in the rpointer are correct and that the restart file exists in the correct location.
