Sansa e250 computer problems
Try using Windows Media Player instead, and see if you get the same result. If it loads in Windows Media Player, then the problem is with WinAmp and not your Mp3 player. When you say it loads half-way, do you mean it loads half the songs and then shuts off? Is the Sansa running on low battery? WinAmp has some kind of update released in the past week - did you download the update, and then experience the problem? It's probably not this, because other users have had the same problem that you are reporting since at least Christmas 2007.
The following is an advice from another Sansa user, so I haven't been able to verify it myself:
"I have to have WinAmp open and a song playing then connect my player and then it will work fine. If I just connect my player then start WinAmp it crashes"
If all of the above fails, reformat your player and start over from scratch. Let me know how everything works out - this is an issue that not even the Sansa website seems to have an answer for.
