Lost space in SD Storage

[FaraTurtle]

I installed Sims Free play on my phone. I clicked this app and it said " The Sims Freeplay requires approximately 307 MB to download and to have a minimum of 664 MB of free space on your device or SD card to run. Select "Download" to begin. Download time may very based on network and location. Wi-Fi connection is recommended.". I clicked download and it downloaded halfway. I clicked retry when it said it didn't connect to wi-fi. After many times of clicking retry i exited out of the app and uninstalled the app from my SD card. My SD card # of used storage didn't change. Please help!

Edit: Fixed! I just unmount the SD card and put it back in.
