Can't see letterbomb on wii 4.3

I've just followed all the steps on wiibrew to install letterbomb on my wii. Software is 4.3e. I give in the mac adress on the site and click the buttom, I copy the files to my fat 32 SD HC card. When I enter the SD card in my wii, I check my inbox for today, yesterday, the day before yesterday and a lot of other days, but I can't see a letterbomb logo. What should I do now? I've tried it/downloaded it a couple of times, but the problem remains...

Make sure the date is set correctly on the wii and that you have played any game at least once.

Date is correct and I just played a game, but still I don't see the letterbomb. I mean, the steps you have to do aren't really hard, so I really don't understand what's the problem :)
Edit: I just tried it with this site: [letterbomb.basst.nl]
I click on the letterbomb file and then I see a blackscreen with nothing on it (freezes). I reboot and try again --> black screen again.
When I try with the original site of letterbomb --> no letterbomb in my inbox
Very strange
