I have been unable to load any cassette programs onto my Ti 99/4A. This is the first time I have attempted to do this in many years. I was able to save a test program onto a cassette, but each time I attempt to load it I receive a "No Data" or "Error in Data" message come up. I am able to hear the sound from the monitor so I know it is getting into the TI. I have tried different cassette players and used different volume settings. Any suggestions are appreciated. I would like to know as well if anyone has seen this happen. Thanks!
