Hello, Well we deleted all files to do with Classic and the preferences, and still get the same error trying to start Classic. Funny thing, it didn't even ask to update the classic components when I tried to start classic again. Ran Mac Sweeper 3.0 for OS X to clean out all log files, removed system caches, and removed internet caches. The hard disk is only half used 20 GB total so plenty of room for programs. System memory is 384MB and Disk first aid finds no problems, but there is. Well back to the drawing board. This is going to lead me back to PC.
