My Sansa MP3 player wont install RockBox because it has the wrong configuration

[Wickedpuppetierman]

I've tried installing Rockbox and for some reason my MP3 player wont let me do it. I have a Sansa e250. It says something about having the wrong configuration or something like that. Please help.
Thanks!

Try giving us the actual whole error message, since they're there for a reason. We can help more then.

Ok...It says Your configuration is invalid. This is most likely due to a change in device path. The configuration dialog will now open to allow you to correct the problem. Then it opens and I click my MP3 player and it repeats what it just said. I'm So cunfused!

Thanks for helping.

What do you mean, exactly, by "I click my MP3 player"?

A single click shouldn't cause it to do anything. And have you tried using the auto-detect option?

[Wickedpuppetierman]

It really weird... I press the complete installation on the Rockbox utility and it says "Your configuration is invalid. Please go to the configuration dialog and make sure the selected values are correct.

[Llorean]

And have you gone to the configuration dialog, and made sure all the values are correct?

[Wickedpuppetierman]

I've gone unto the page but I don't know what to do with it. I've tried messing with it but it still gives me the configuration problem message.

[Llorean]

What happens when you try the auto-detect?

I seriously need you to be clear with "what I've done, what exactly I click on, and what it tells me when I do." It's impossible for me to know what you mean when you say "I've tried messing with it."

[Wickedpuppetierman]

Sorry. Ok, First what I did was I clicked the Rockbox icon on my desktop. Then a message appears that says "Your configuration is invalid. This is most likely due to a changed device path. The configuration dialog will now open to allow to correct the problem.

Then I clicked "ok".

Then a box appears and it says "Select your device in the filesystem." And it has a blank box to type in. Then right below that it says "Select your audio player" I then clicked Sansa e200 and then ok. Then it says "Your configuration is invalid. This is most likely due to a changed device path. The configuration dialog will now open to allow to correct the problem." again. I don't know what I'm doing wrong. I'm sorry I was being so unspecific before.

[Llorean]

So you never told the program where to find the device in the filesystem.

have you tried the autodetect button like I suggested earlier?

[Wickedpuppetierman]

No. I didn't try that. I can't find it.

[Llorean]

Lower right hand corner of the configuration screen where you pick your device and device path.

[Wickedpuppetierman]

Ok, I installed it now It won't let me add music or games or anything. It says the path and configuration is messed up again.

[Llorean]

Is the player showing up as a drive?

[Wickedpuppetierman]

I go to my computer and click on the Sansa MP3 player and for some reason it says "Choose the program you want to use to open the file with." I have no idea whether it is showing up as a device or not. But when I first plugged it back in it said it had discovered new hardware.

Whenever I replug-in my MP3 player it says "Exception Processing Message c0000013 Parameters 75b6bf9c 4 75b6bf9c 75b6bf9c."
