Hello folks, 
I just tried logging into the Silver server and got the error message "Invalid Username or Password".  However, when I log into Gold with the same account info, it works just fine.  I do want to play silver because I have no progress on Gold (so it started by introducing me to Prof. Oak when I tested to see it worked on that one).  Some information that could be related to the problem: 
1) I just merged my Red/Blue accounts with red as my main account about 15 minutes ago 
2) I just changed my password because I couldn't figure out how to log in about 20 minutes ago 
3) According to the Dashboard, there is a different IP address associated with my Silver account than my Gold account 
4) The information I entered IS correct (checked character for character) 
Could this be because I just recently changed my password and the game hasn't registered the change yet?  Any help would be greatly appreciated.   
EDIT:  A second password reset solved the issue.  Anyone else with a similar issue should look at this.
