for one thing, remember that it will only pick up accounts that have actually been POSTED to. (Not just entered, but visible when you run a Trial Balance in the GL)
Also, be sure to check at the bottom of the screen to see that you are actually using the default company that you need to pull accounts from. (Remember it is UNRELATED to the company you logged into SL with!)
Also, when you ran the scripts, did it tell you that the length of the account was correct? (but usually the symptom of that is getting underscores in the wrong places)
