Error When opening D3 - "The application encountere a Error"

Anyways, So since I have started using this software i get a really random and annoying error.
This is the error

Sometimes when I Load D3, it will start up, sometimes it wont and i get this error after the D3 Decal comes onto my screen for 2 seconds.
70% of the time I get this issue.
I have searched the forums and tried everything people have suggested and nothing is working at all.
In fact, I have formated my PC, Freshly installed Diablo 3, ISBoxer tools/progs and all the required things for it like .NET Framework 4.5 etc, and it made no difference,
If someone could please please please please help me as i just want to play my 4 wiizards, that would be really really good

I have ran out of options and payed for a software that isn't really working for me so please help me !!

thanks!
Anthony.
