why am I prevented from accessing my account.?

Hi mackwilhelm
 
Welcome to the Communitgy Forums.
 
Would yo be able to give us a teensy weensy more information to go on...such as which account you are referring to and that you do not have access to?  I can try to guess but it always helps to have as much information about the issue before starting to try to help.
 
Many thanks in anticipation.
