Can't transfer from my PC

[Minnn]

Hey there,

Can anyone help out with this?

I can log into my account.
I can download.
I cannot upload.

I'm receiving error 550 Access denied: Your firewall server denied this operation.

Weird thing is, I CAN upload on a different PC under the same login. It's probably one stupid little setting I haven't transfered over to the new PC I've gotten. Anyone know what it could be?

Cheers,
Minnn

I've tried using two different domains hosted with different companies now and I'm still getting the 550 Access Denied error. So that determines it's a local problem at least.

Anyone have any ideas about what's stopping the files from uploading?
