Thank you BWinmill and PeterT. At least, I did what Peter said about doing the set-up with the computer and deleting the .tgz file, and everything worked fine.
Also, everytime I sync I will have to erase .tgz file, but I don't use that too much.
Lucas Malor: I haven't found any bug, but I didn't like the Aura feel and the design unconsistency. I prefer the old one, with more contrast and minimalistic.
