I downloaded AND PAID for Switch 8.32 for Mac yesterday. It worked okay. Today I get onto my computer and Switch won't covert flac files to mp3, which it did yesterday. When I drag a flac file onto the program window. it will play when I press the green triangular "PLAY" icon but when the I press the "convert" icon, it just says "Conversion failed". I didn't pay them good money to just to see "Conversion failed". I tried to contact NCH and they want some sort of number from me before they'll take my call, even though I am a paying customer. They didn't give me a number but, just as there is no doubt, THEY TOOK MY MONEY alright. Thankfully, there is a 30-day money back guarantee, but I don't want to exercise that option as I want to use the software. Now here's the thing that stinks, they accept email reports but say they will get back to me sometime.
