It means your ace3ds plus is an old ace3ds plus that can not work on your latest 3DS or DSi. currently the ace3ds team haven't released the update patch yet. and i doubt they will release it in future. they just released a new card for the latest 3ds and dsi. if you just bought the card a few days ago, then the card you received is not a pre-updated or pre-flashed one, just contact the reseller to replace it for you. if you bought the card long time ago, then you can only wait until they release the update patch, i guess they won't release the patch anymore, and recommend you just buy r4i gold 3ds, (this one: http://www.thegamerdepot.com/buy-wood-r4i-gold-3ds-card-for-3ds-xl3dsdsids-p-150.html ) always release the update patch quickly for the future 3ds update, wood firmware support.
You can choose ACE 3DS Plus which working on on 3DS 5.1.0-11 from www.depot4u.com blue package or pink package is available
