Mate, you should not have created an EE profile without having received the ECA report. If you don't have a Canadian degree, an ECA report is mandatory if you want to claim points for your foreign education.
Since you received your ITA on your (incorrect) assumption that your education was equivalent to a Master's, you now have insufficient points under that draw and your application will be declined.
If you proceed with the application, they can also technically charge you with misrepresentation because you did not have the ECA report when you said you did (at time of ITA).
I would advise you to decline your invitation and rejoin the pool with your new (lower score).
Cheers,
Dex
