I really need help or advice on how to solve this problem. I have a mid file whose size is 20363. Below is my gcd:
[code:1:0f92875f94]
Content-Type: audio/midi
Content-Name: RockyTop
Content-Version: 1.0
Content-Vendor: R&M Workshop
Content-URL: http://rmworkshop.com/phone/rt.mid
Content-Size: 20363
[/code:1:0f92875f94]
Then file attemps to download file, when it is done, it give the 905 error.

Any help would be great.
