Forum:ED-E and Arcade Gannon problem!

So I have two problems that i encountered in the gameplay:

1. ED-E My Love quest: I cannot talk with Ignacio Rivas, he is always telling me "what have you done?", is it because i activated archimede and killed the ncr soldiers?

2.Arcade Gannon quest: i spoke with arcade gannon about his past, i chose to help him with his past problems, but no quest appeared! I mean for aude lang syne is an unmarked quest or?

P.S. i play PC version
