I know, I'm such an idiot, but I swear this WON'T happen again:
I've asked for a new key code or something from Enterbrain (since Protexis doesn't provide them any longer) with my 2007 keys because RPG Maker XP was asking me for a different code than the ones I have on my paper. I received their response, received the codes, activated the product and started using (once again) RPG Maker XP on my Mac (with Wine) since my PC got all f**ked up.
I had that e-mail on my MobileMe with the new codes until I've upgraded my iPhone to 4.0 and lost some quantity of mails (and notes), one of them being this particular mail (I don't even know what one has to do with the other).
Thing is I would like to activate it on my recent netbook to have the program on both desktop and portable computers to keep my projects with me all the time.
I don't know what to do now but I just don't want to piss the company again asking for my keys back. Is there any way I can retrieve them from my Mac instead?

Thanks

The short answer is you'll prolly need to ask enterbrain again. It's thier own fault as thier program is not like most programs where you can click on help and about and it displays "registered to <name> <serial>" sadly thier program doesn't do this.

They wont get mad at you likly they wont even know your the same person whom asked for the code before they will just check your registration info and if it matches give you a code. All they care about is avoiding piracy of their products. They shouldn't mind giving the codes again. Get an email account like gmail that gives you unlimited storage space so even deleted emails go into a folder and never get deleted. Then you won't lose important stuff like this in the future.
