That almost sounds like there is a problem with your driver disk. TOS Error 35 means a file could not be executed.

"TOS Error #35, probably the most common error alert that is not self explanatory, happens when a program you are trying to run has somehow been corrupted. What it means is that TOS can not find some magic numbers it expects to find either at the beginning or at the end of the program file. This error is usually attributable to operator error (as in trying to execute an archive or text file as a program), or to bit rot.
You may need a new copy of the hard disk utilities.
