crashing on large files

 Quixpin DJ crashes every time I try to load 2 mp3's of about 20 mins each. It loads the first one ok then crashes when I try to load the second one. I noticed someone posted something about crashing and you had a couple of questions to be answered... I have attached and answered them here just in case.
 

-Can you provide information about your device, what version of the OS you are running, and if it is jailbroken?
Iphone 3gs, ios 4.1, not jailbroken
-When does it occur? Are you doing something like loading a file when it crashes?
When I try to load 2 files of about 20 mins in length. It loads the first one fine and crashes on the second one.
-How large is the file that you've loaded?
One file is 30mb and the other is 20mb.
-Is there another file playing at the time?
I tried it both ways. I tried just loading the files first and then tried loading one, starting it, and loading the second... same results.
-If you are loading a file, is it the first time you've loaded the file?
No, the files load individually fine.
-Have you set your iTunes up to send reports back to Apple? This will send us crash reports. Perhaps we can get more details.
Yes.
