Store not working. Crashes upon clicking store.

Windows 8.1 Ram- 8 gb Hard Disk- 1 Tb

Opened League client today. I clicked on store and it would load for 2 seconds before getting an error report saying that the client has crashed. So I have restarted the client about 5 times and got the same report. Then I tried running it on administrator and still crashes. Also, I have tried restarting my computer and also clicking repair on the client and tried accessing the store but still crashes. Any fixes?
