I have all my music on a 4GB flash pen and I have had a new computer and I am trying to get the music from the pen to my computer but it keeps asking me to format it.

Still having problem.

Well, I'm not sure what you can do to it to fix it. There are some tutorials around for things like this, but when a pen asks you to do that, it usually means the file system is corrputed. Most repair attempts are going to be possibly disruptive/destructive to the filesystem - but personally - i would NOT format it, and attempt an undelete or similar job using software like GetDataBack/FileRescue which seem to be better. Try another computer otherwise.

I get errors when ever I try and run any exe's

Your flash pen is corrrupted. You can try but I have seen this before, you have to toss it or bring it back to where you bought it. The flash memory cannot read the files so they are stuck.

i had a similar problem and i brought it back to the store and they exchanged it for me.

If you formatted any of your drives with your flash pen plugged in at the same time you messed up your directories and files on it. I never found any possible way of getting these fixed. Perhaps a unformat or undelete software could work, it may be worth a try as a last resort.
