Now I may be wrong here but there are lots of programs that have parts which can only be used a number of times before you have to buy it. The one I'm think of was one of the Nero versions, it was the full product and came with a MP3 encoder but until you actually bought it you didn't discover that the MP3 bit was an optional extra that you had to pay more for. It too worked about 20 times before it stopped working. There were quite a few people angry at that one and that I presume is why they stopped doing it. It may be your Pinnacle is the same. You can get MP3 programs on Freeware which would do the job.
