Does anyone else have the problem of crashing just after the splash screen?

Note: Windows 8.1/Intel HD 4000/8Gb

Originally i had a problem with LavaSoft, and it crashed on startup and threw an error. Fixed that.

Now i get to the splash screen, and the editor window just sits there empty.
Task Manager shows the process, but nothing is happening.

I have tried:

1. Reinstalling HD 4000 drivers.

2. Using command line to force OpenGl and D9

3. Removing all older versions of unity from the file system including AppData

4. Uninstalling and removing almost any mention of Unity in the registry.

This is the log file.

The really sad thing is i had Unity 5.3(i think) and it worked fine.

I uninstalled to have a clean install because i bought pro and an accelerator package, now i can not get it to start at all.

Anyone else have this problem? Or even better a solution!

Thanks Owen

PS. Getting really frustrated as i tried to enter my code for pro and it said it was invalid? Do they expire? I bought ti May 31? I have been trying to get Unity to work for 5 days now.
