Colorado Workers comp. No work and no compensation. What rights do I have now? Is it too late to take legal action.

I was involved in a trucking accident on 10/30/07. It wasn't my fault. The owner told me not to worry about anything and that the company would take care of me. My injuries were severe enough that I couldn't return to work until 07/20/08 (I received a letter from the employer stating I had to return to work). The first job I had was to make a MSDS booklet for the company. How ironic, lack of safety procedures was the reason for my accident. The company had a truck safety rating of 93 on safe stat .com at the time. The state could be held responsible. There were 2 driver fatalities after my accident. I reached MMI in March of 2009. I was released with permenant restrictions. I settlled with the insurance co. and was "cut loose" by my employer. I can't find work. I can't receive UI benefits.
