Use the included buymysys.exe program to get that PC's HID (Hardware ID) code, where mysys is intended to run.
Purchasing mysys will give you unlimited use with no expiration on the PC used to generate the HID code.
Once the paypal payment is processed, you will receive a mysys.lic file to be placed in the program folder. This process is automated and you should receive the file via email within minutes.
Only $29.95 USD to warp time! Good deal!
