SD card not showing videos!! HELP

SO I wend on a tuna fishing trip last weekend and used my gopro3+ to record the trip. Well i plugged the 16G micro SD card in my computer 2 days ago to review the footage, and an error message popped up saying "an error is preventing the video or photo from being displayed errroc code 0x8000000a"

so i unplugged and repluuged the card readerback in the pc and it worked.

well get to yesterday the same thing happened, and it prompted me to scan for issues, so i did, and now the videos are gone.....!!!

The sd card is still showing it has 7 GB of data on it, but there are no videos shown on the card. ive clicked the show hidden files button, and a few random folders,not videos, showed up, but not what i am looking for.

ANyone know what happened or how i can retrive this? or maybe a place i can bring it in baton rouge to get the information back?
