Not having a D-Link router, I can't offer specifics, but if it used to work, try these:

1. As blakcheez suggested, refresh the firmware in the router. Cheap and easy.

2. Reset the router as it came from the factory. On my Linksys router there is a recessed button to accomplish this.

3. Find the port security table in the router (it may be named differently, but it';s the table that says what activities can happen on which ports) and make sure port 21 is wide open. It is usually open only inbound.

4. The DMZ is usually a bad idea unless you understand and have addressed the security risks, for example with a software firewall.

5. Speaking of firewalls, make sure the Windows firewall allows Port 21 as well, in both directions.

6. Any way to upload to some other FTP server, just to test? Not forever, just to see if it's something weird with the correct server.

If these don't help, tell us what you did/tried and we'll go from there.
