[EnergyPlus_Support] Re: EnergyPlus V7.0 and OpenStudio Legacy Plugin 1.0.7 released.

["Ignacio" <nachogo27@xxxxxxxxx>]

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
