Received the reg code...but I have a few questions

Fist I want to appologize for the uproar I created earlier, but I am strongly opposed to your registration process. Hopefully the debate is useful to you in some way. If not, pull the damn thing. You won't hurt my feelings a bit. I know you guys are busy doing your best to get a patch to us so don't feel obligated to answer this message right away.The questions I have pertain to registration (who would have guessed?). I have heard several scenarios where a user would have to re-apply for a new reg code. I have read on this forum and in your email that if I install to new hardware or move the 737 to new hardware I will need to re-apply for a new reg code. Will I have to re-apply if I 1) delete your product and re-install it; 2) remove FS2002 and re-install it and the 737; 3) reformat my hard drive and re-install everything; 4) add memory; 5) add new hard drive; 6) restore to the same PC from a backup? Can I use the same reg code to simply re-install to the same PC that hasn't been changed? Can I re-use my registration code at all?You don't have to answer these questions quickly as I am quite happy with your great product as it sits. Just thinking of future possiblities.Keep up the good work,
