Thank god I caught you in time. I don't know who sold you that OS but it's not DOS. Get a proper DOS then find the "TMO DOS Enterprise Edition". You might need a pc upgrade. Or at least a pc.
Btw, joke posts m'key, joke threads hmmm.. not m'key. In your place I would've posted this in the SH5 game spec thread.
For files I use Filefront, it's free and fast and no waiting time. For images I use Imageshack, you don't even need an account for that.
