I figured out the problem, I just changed my password on MU account which has "!*%" in it, and after I changed back to normal letters, it worked.
I suggest you fix this problem because the password with these letters will be safer.
I also notice about the "my site earning", seem it's not working, I didn't have any sales for about 2 months since I joined this program. I Don't know if it's just me or for all others?
1 more thing, do you have any special offer for webmaster (not sales program).
Anyway, thanks for your response
