Windows phone can't read micro sd?

Using the nokia lumia 635. Not sure which windows it's running. It read all mp3's and wma's just fine. I tried to transfer all songs and pics to a 64gb micro, but before I did I cleaned out some of the old android stuff from the previous phone. Apparently I deleted a few apps from the windows phone which made it to the card. So I "uninstalled" them from the handheld and tried to re install them, but half of them wouldn't budge. Tried restarting repeatedly then gave up. Half my music library didn't work, and then the other half stopped too. I have a file manager that lets me open the file in the card manually, and there all songs will play, but the music player magically can't find them there anymore. I can't imagine what I could have deleted on the sd that could reduce it's capability like this. The windows music player is on the phone, not the card. I tried it with the old card again, same story. I think it might be a phone problem, but I didn't change anything about the phone. Currently looking for a system default settings button. Do I need to go that far?
