Groove 2Hn as a Wireless AP

I’m doing some testing and I have a Groove 2Hn, I’d like to set it up as a Wirelss AP for multiple devices, I found a guide, http://wiki.mikrotik.com/wiki/Manual:Making_a_simple_wireless_AP, but I get the following error message when setting the wireless mode to ap-bridge

couldn’t change interface - license does not allow AP mode (6)

This is the following from /system license print:
software-id: UKC8-UBPD
upgradable-to: v7.x
nlevel: 3
features:

Should I be able to configure this model as a Wireless AP for multiple devices or do I need to upgrade to license 4?

Thanks.

LEVEL 3 License does not allow Access Point. Level 3 is intended to be used as a client.

You will have to buy a new license, or a different routerboard.

See this page for license information:

Cheaper would be to get the correct model instead: http://routerboard.com/RBGrooveA-52HPn

(it has the letter A, which is AP)
