After I upgrade Wilcom designer ES45 version 6 (Parallel Dongle) to version 8 (USB Dongle), I can not use my old dongle for earlier version anymore as the access codes was changed while dongle is updated.

While you have posted a statement, you have not asked a question. If your question is how do you crack the dongle you need to read the BIG RED LETTERS at the top of the Forums and then read the FAQ. Read the FAQ and then try a question which is more focused and shows you have done some of your own work. We are not here to do the work for you.
