Okay with the clearer OP I think I know what was going on
With regards to the account missing or whatever it was, It was possible that the services you tried to use (being steam profile and email check system) were not in sync at the time....
What I mean by this was that when you created your profile, there might be a delay for when steam updates all other applications with your account details (an application example would be "password recovery")
As for your flash not working, try making sure Flash is installed and working on IE and your default browser. You may need to reboot your computer after this is done
Oh and +rep for rewording your OP like I asked and not freaking out on me
It was so much easier to understand what you asked now
