key generator does not work

so you download a key generator, it does indeed spit a code - then what! The program wants to go on line, and immediately says invalid code - what am I doing wrong?😕

What are you talking about exactly?

Please be specific about the application and the exact problem you are facing. We are no oracles here, you see...

P.S.: Presence of words like "key generator" might be considered as offensive to the CE spirit, since we don't support software copyright infringement here !! (I hope I did good by avoiding the P* word 😎)
