3510i issue, please help

[Rub1]

Im currently using this "setup"

- A fbus/mbus datacable
- 3510i v4.01
- MobiMB 1.2.3 *cracked*

I can download pictures from my phone to my computer, and it shows up correctly on my computer screen, likewise with midi's..

but, there is a HUGE but.. :(

I can't play them on my phone, it says unable to open file when i access it from my phone.. this happens with midis, pictures i transfered from my pc (right format and res) and games.

I got 100% on those cable tests, both fbus and mbus.

I hope you can help me out.. this is really annoying.
:mad:
