pfSense: 2.5.1 x64
Switch: Dell Powerconnect 2824 and 2848

I configured my 1st pfsense, DNS, DHCP vlan1, squid are working ok.
I'm trying to create vlans but I can't get them to work, I don't know what else I can do to make them work.
I saw this video https://www.youtube.com/watch?v=l3GNKKt9WMc, but I couldn't get it to work.
Switch has a LAG on ports 21-24 and 45-48.
I tried factory reset(serial port) unsuccessfully.

VLANS Config on pfSense:
VLAN 1: 192.168.0.0/24
VLAN 200: 192.168.20.0/24

VLAN\VLAN Membership config:
VLAN 1 default config
VLAN 200:
Port 1 Tagged pfSense
Ports 13-14 Untaggeg Windows

If I set VLAN(200) on VLAN\port settings, the client computer does not get the IP (192.168.20.0/24) via DHCP (static IP doesn't work to, I tried ping between PCs)
If I leave it on vlan 1, it gets the IP of the range 192.168.0.0.

What am I doing wrong?
