How do I fix appcrash on my program?

I'm trying to use a program calling Vz in-home agent that Verizon gives you when they give you a router for internet. Every time I try and open in to get it running it brings this up. I made it smaller. And its not only this program. At random times I will get other pop-ups of other programs that crashed that I have no idea of what they are. Please help! Thank you. Oh and I also did what this guy did on this site. and this too. but nothing worked.
