Unfortunately the law allows for the judge to take that time. Perhaps you can approach the information and assistance officer at your venue and ask them if they would approach the judge to request the judge to expedite the matter. But again if somebody already mentioned there is no longer requiring them to do that.
I'm a bit unclear about your situation. Did you actually go to trial on your case, or did the judge ask the DEU to rate a report which was the basis of a settlement? If you went to trial and the judge issued rating instructions, and you just got the rating, both sides have time to object to the rating and move to strike it or to cross-examine the rating specialist. After that time, the case would stand submitted and the judge's 90 days would start to run.
When you say you don't have the 90 days, what do you mean? If you are not working, you probably should be receiving permanent disability advances, depending on the rating and on how much was previously advanced. If nothing has been advanced, a call from the Information & Assistance officer may get you some retroactive payments.
Of course, if you actually have an attorney, you should be asking your attorney about this.
