32GB Extreme Pro help

i recently purchased the card and used it 1 week with my camera then all the sudden bam… it wouldnt write pictures to the card, so im freaking out because my sisters wedding is on the card so i am trying to get everything off the card onto my PC but i cant seem to do it… when ever i try via, directly plugging camera into PC or using 2 different card readers windows seems to run extremly slow and even freezing occasionally. a couple times i have gotten to the folder and been able to copy but it is transfering at about 150kb/s, with around 17 GB needing to be done…

Now i cant even get to the copy point, when i right click to copy it freezes up and says not responding.

If anyone has any advice or help i would much appreciate it. Id really like the wedding pics :frowning:
