i have 3.3.84 installed been working great now it wont open this morning with a full day of dynoing. What can i do!!!  help

Any luck getting it to start? I too am experiencing this. I have rebooted the PC, uninstalled and reinstalled the software, tried as administrator, tried compatibility mode, etc. No errors or anything, just doesn't open. 

I was able to download an older version, copy configs, uninstall and get the new (older 3.3.59 & 3.3.71)version running. I need to research what the latest stable version is but those were both mentioned on the downloads page.

@forcedfour I was told go back to and load 3.3.81 and it worked

hi everyone, yourdyno v3.3.84 won't start were can i get a old version please?

Yes, there is a global issue. Uninstall and reinstall 3.3.81 or earlier. https://yourdyno.com/YourDynoInstaller_3.3.81.exe

I will fix when back from vacation in 1 week. 

I had to delete all the files/folder also, once I uninstalled; that was the only way I could get it to work. But I did get it working yesterday.
