Dreamweaver cs5.5 suddenly started crashing when it starts or right after it opens...

Question

OMG so frustrating, my dreamweaver cs5.5 has started suddenly started crashing either during the splash screen or right after I choose a web site to work on.
YES I have red the forums and tried EVERYTHING, deleted my preferences, made a new account, re-installed three times, editing the registry, done it ALL.    It seems to open now in a temp Guest acct with Admin privileges but I can't access any of my web site files, it's really not usable this way...what can I do?
It crashes during this...  even though I have cleared the site cache several times.....
How can I have this expensive of a program just not work.....HELP, I have tons to do and can't use my software!
Please someone help!
I even CALLED Adobe and tried to PAY for help....      this is shocking to me after spending tons of money on Adobe software..
Thank you ahead of time.

Answer 1

Here's exactly what was at the bottom of my bum css file:
/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */
/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-sm-min) { ... }
/* Medium devices (desktops, 992px and up) */
@media (min-width: @screen-md-min) { ... }
/* Large devices (large desktops, 1200px and up) */
@media (min-width: @screen-lg-min) { ... }
So they were completely empty...I just stuck them in there because I wanted to add stuff in there...not sure what I will do now..
Interesting just FYI this is a web site which is utilizing Bootstrap...so these MQ came directly from the getbootstrap.com web site...
