Why isn Ion working?
Make sure you send ion.83g (if you have a TI-83) or ion.8xg (if you have a TI-83 Plus). Then run prgmION to install Ion. Finally, run prgmA to start Ion for the first time. If you do not have any Ion-compatible programs loaded, Ion will not start. Note: SOS and AShell programs will not run under Ion. Do not ungroup Ion! Read the Installation Instructions! If all else fails, try resetting the calculator and resending your files. Some programs, such as Diamonds, require external levels to be loaded to run. Make sure you have all the required files.
