Can't install MIB toolbox on my unit

[TTTuv95]

Hello,
Before writing this post i searched through many posts/forums and it seems im the only one having this issue. I can't get MIB installed on my unit via SD card. I tried few different SD cards but outcome is always the same "No valid update data found on the medium" i think i tried every possible way to format different cards but nothing seems to work. Is it possible that i can get it working only through D-Link ?

I downloaded and istalled POI via SD card and it worked so faulty card or SD reader is not valid.
Thank you in advance for any solutions that may help out !
