Acekard 2i DSi XL not working --->Father needs help!

Just got a new Acekard 2i that is supposed to work with the DSiXL.
I have tried all the step by step instructions to get it going but no luck.
I could really use some assistance here.....I put the latest version of AKAIO 1.8.9 on the root
add a game or two.
Put it in the DSiXL....
Nothing... slot appears empty to the machine.At this point I assume I need to do an update.
I have my son's older DSi Lite. so I think i'm good...
I put the necessary files on the kard (AKAIO 1.8.9 and ak2ifw_update_3ds42_dsi144) .... put it in the DSi lite.... and nothing.
Yet his R4 kard works just fine?I could really use some help here.
I would be forever in your debt.
Thanks again!

It sounds like a contact issue, the acekards a well known for them http://gbatemp.net/topic/231412-solving-acekard-contact-issues/

sorry I will give more detail.
after I add the necessary files to the card the DSiXL gives the following message
just a message saying
"There is Nothing inserted in the Game Card slot"
I even tried taking the memory card out and got the same message...
I will have to address this later as he is heading out of town for a week.
I was hoping to get him set up before he left.
Hopefully you guys can assist once he returns.
Thanks in advance!
