Has anyone tried this thing out? I bought one and it's not working. The ports show up but if I disabled I can't re-enable them and the macs are all weird. I tried to configure a port but doesn't show a link status.

make sure you have latest RouterBOOT and RouterOS installed. Then make supout.rif file and send to support at mikrotik

So I did what you said and sent the supout.rif into support. What's really interesting is after I installed the ROS5 beta the card started work but only for like 20 minutes. If I reset the routerboard it works again for a while then stops again. The macs are all wonky and resetting them doesn't put them to what the sticker on the bottom says they're suppose to be. Is this card suppose to work with ROS 4.6?
