Thanks for your submission in the Error Form. I've looked over your problem, and it seems you are having the capability and archive corruption issues. I've verified in an emulator that this program does work with the TI-83+/SE, but does not work with the original 83. It should work with the 83 Plus. I see that the program is getting corrupted in your archive, provided the screenshots you submitted. Avoid constantly archiving and unarchiving the program. If XFILES is the only archived variable in the VAT, it can become corrupted after a garbage collect. For best results, keep this program and RAM and keep the App Var containing the pure version of xFiles (the name is xFilesUp). Avoid tampering with the App Var (Editing its contents, constantly moving to and fro Archive, changing its name). Be sure to send the App Var AND the Update program (XFILESUP). Don't interrupt the process of installation/updating. If you are having problems with version 1.03, try older versions of the program and test them out. Good luck!
If you are having problems sending the program, try coding it from the source. I know, it's over 1000 lines of code. But if your that desperate for the program, you could try that. Or use an emulator instead.
