I’m experiencing the same problem. Old password doesn’t work and when requesting a new one, the download web service informs that it has been reset
and sent by e-mail but it never comes through.

Subject: [EnergyPlus_Support] Re: EnergyPlus V7.0 and OpenStudio Legacy Plugin 1.0.7 released.
Hello guys,
I'm having problems to download the new version.
I've tried with my old pass but it didn't work.After that I requested for a new pass but I didn't get it on my email(I've checked the spam folder).
Is your pass working now?
Thanks in advance,
Ignacio Gomis
