Princess Spacy: Changing birthday and my name

Hi! New to tamagotchi...since about 2001 that is. But, it's much different now! I have a a Princess Spacy ID L. So far I feel like I'm getting the hang of it even though it's in Japanese with the help of this website. But, a couple things I can't figure out:

1) How do I change my birthday and name without resetting and losing everything? I can't figure it out. I tried to change the main date one time and then when I went back to the main screen it said Happy Birthday haha. I'm not sure how I fixed it i was just fiddling with things and it worked one time.

2) Can you use those ID L passwords to get things like McDonald's on the Princess Spacy version? I can't find the section where you enter a password.

I bought a Sigma Tel IrDa usb but it doesn't seem to work with any computer I try. I am going to order a different brand I guess. Oh well. Any help would be appreciated! I am really enjoying this!

Right, and also, I hear IR USB's aren't very reliable, so I suggest using a cellphone with IR instead. You can buy a cheap, used one for like $15, and some Samsung Galaxies even have built-in IR.

I have the IR USB and it works, it isn't always 100%, but it gets the job done.
