As long as you are still within the statute of limitations, you can re-file the case and basically start over. A lot of the work can be duplicated, though, and you will likely need a new attorney. Your new attorney will have to collect the file, and determine what injury liens are binding on the file and if you have to pay your old attorney.
If the statute of limitations has passed, you will want to evaluate the case for attorney malpractice. I hate to say the dirty word, but blowing a statute of limitations is the big one.
You need to refile, before the time in which to do so expires.
With NEW counsel. The NV and your county bar associations can assist with referrals.
