I agree, on Black I have made no trades at all and can get into the Dream World. On White I think I have made about 10, with only 6 on my "Trade Pals" list. I hope if this is the reason, then it gets sorted out soon. At least my Black version works!
Actually, I have traded with 20...
Is anyone still getting the "Processing Registration Data" message? After 11 hours of tryng to get in with smoochum, I woke it up. The game allowed me to tuck in another pokemon, a happiny this time, but I am still getting the same message!
What should I be doing?!
First (not including Red Gyarados, which for some reason didn't really count to me as shiny as it is very easy to encounter) was a blue Nidorino in Gold. I was searching for chansey at the time so my first reaction was 2Why aren't you a chansey!?". This was about half an hour into my search...
I'd say the trainer and part-time co-ordinater but mainly a pokedex completer, as catching pokemon is always my favourite part of the games. I'd also be pretty explorative and breed and study pokemon too.
