Can't start

hello!

i’m running on 18.8.71 and just downloaded 18.8.80, but like i said, can’t even start, rolled back to .71, any log i can see?

You need to provide additional information. What exactly do you mean by “Can’t start?” Do you get any error messages? If so, post a screen shot. If not, what happens? And what operating system?

well can’t start, double click but nothing, 0, nada.

It sounds like you did not install properly. When upgrading, you install exactly the same way as you did the original installation. You do not uninstall anything first. Your data file remains in place and is called by the newer version of the program.

Try reinstalling to see if that fixes things.

no effect

look like that 81 build fixed this.
