NOt sure about the trial limitations, but with FULL version, just choose to do FULL erase, go drink a couple cups of coffee or a soda, and in 45 min to an hour, it will do its "erase" job. I have seen in print that the "full erase" that Alcohol does is actually more of a "format" function. I have used it on 10 Fuji DVD+RWs without problem.
