Cannot load graphic card driver

Hey guys, don't know if any of you guys encountered this issue.
So I have a Blackmagic Design Intensity Pro 4K card, and I've plugged it into the only PCI slot that it can fit on a Ubuntu workstation.
Then I tried to install driver and everything following the read me file.
Then I cannot load it, and I can not see the card under lsmod.

Anyone here can help?

qatest@qatest-Vostro-260:~$ sudo modprobe blackmagic

And if I launch Media Express, I'll see error message "Blackmagic hardware could not be found in your system. Please check the installation"

BYW, I saw someone had same issue, but he didn't explain how he resolved that.
I am not allowed to share the URL of that topic, the title is ""No Desktop Video device detected" Desktop_Video_Linux_10.5"

Thanks in advance

What are your system specs, i.e. motherboard, cpu etc, what cards are in the system and in what slots?

Hey thank you for the reply. I've found the reason I have this issue is cause I installed with deb\i386 rather than deb\amd64. Seems amd64 is the one for 64 bit system no matter you are using Intel or AMD. That's why.

I am facing similar issue with latest driver - Can anyone explain if they got it working and what did they have to do get it working?

I did install a 64bit driver and no luck.

Please someone help.

Update: After digging a bit found out that the module is built correctly but not signed.
See error message :

modprobe: ERROR: could not insert 'blackmagic': Required key not available
