Please stay in one question.
You've started a new question with this post as you did with your request. It's easier for me to have one question, containing all posts regarding that question...
That was no answer for your question. Here we go
As you can see on the download page of samsung, there are several applications available. It's a bit confusing, as they have
Multimedia Studio (1.0),
Samsung Music Studio (1.0) and
Samsung Media Studio(5.1.3.2).
I think you should just download Music Studio. This is a
direct download link to the installation file. Since the Multimedia Studio doesn't work, you can uninstall it.
Also something to check, is that because the player is recognized and listed in the Device Manager, it probably is available in
My Computer.
If not: right-click
My Computer ->
ManageSelect
Storage ->
Disk ManagementYour mp3 should be listed there as an 20GB drive.
Let me know what you found.
