learning to use the yepp audio manager(version 3.4.111) is a nightmare to me. I use it to download music to my yp-30 mp3 player. the software was so badly designed. I was so madly trying to understand how to use it. this is the worst software i have ever seen. after i was clear how it works, i just can't believe why they made such a stupid product frustrating to use the yp-30 player is pretty cool, it is definitely a classic design. but the managing software is a big loser. i think the manager for yp-20 is much better than this.
