I came across this wonderful place yesterday when trying to find answers to my problems. This is a great community! I'm not really new to the ATRAC arena, but my new computer is. I just put Sonicstage 4.3 on my new computer (Windows XP Media Center 2005), and imported my 9700+ mp3's into the program. I was able to convert some of my collection on my old computer with Sonicstage 3.4 without any problems. When I installed Sonicstage on my new computer, I had the OpenMG module can't be found problem, but with the help of this forum I was able to fix that. The main problem I'm having now is when I start to convert a number of MP3's to ATRAC3Plus (any bitrate) it will encode a few songs and then just close. There is no error message. The program just quits. It seems to be randomly converting files from my selection, but gives up part way through. Has this been heard of before? I read about codec packs causing playback problems, so I uninstalled all of my Codec packs. Any other suggestions?? EDIT: After checking out the rules for posting in this forum, I offer the following: My computer has an AMD Athlon 64x2 3800+ CPU, 2 GB of ram, 1 HDD of 320 GB and 2 of 500 GB ea. I didn't have any other software running when I started this, and am fully up to date on all windows updates. I reinstalled all of the MDAC files, and windows had some additional updates for me to install. I have tried going back to Sonicstage 3.4, and then back up to 4.3 with no success. I have a Sony CDX-510 CD player in my car, and already have one ATRAC cd I have used for the last 6 months or so. I hope this new info is helpful
