The game client wont open for me

when i click on the icon the little league icon will pop up for a few seconds but then disappears. I went through the boards and saw that some people had solutions but none of them worked for me. When i open the task manager i can see that a few icons show league is running but then after a few seconds it disappears. the only way i have gotten it to work is by uninstalling and reinstalling but that only works for one session and after i close out it refuses to open again.,
