GameZ launcher wont open

This started last night, it started when my power went out on my PC while i had the game running, after i turned my PC back on and tried to boot the launcher nothing happened i checked the task manager to see if it would pop up but it only appeared a couple of seconds and would then close, I tried repairing the launcher but i still had the same problem, I even uninstalled the launcher and install again but i had the same exact problem. Someone please help me solve this.

Update- I found out that in the files there is another .exe file labeled GameZBD.exe.old which i renamed to GameZBD.exe (removing the .old) and running it actually ran the program, But it says "Updating Launcher" and it gets stuck at 100% and never goes past that. (I will leave it open for 24Hours too see if it actually finishes "updating")

 

-Update: It did not work i still cannot open the launcher, I guess i will have to quit GameZ and go back to Na or something unless I find a fix soon or someone else helps me out.
