[Solved] Unity 5 grey screen on startup

I installed Unity 5 and when I start it up, it shows the unity logo then goes to a grey screen:

I have tried:

• Uninstalling, restarting my pc, then reinstalling

• Restarting my pc

• installing nodejs into the unity folder (before the uninstall)

Useful info:

• Unity version 5.4.2f1

• Windows 10

• 64-bit

I also have Unity 4.6 installed, but they are in different folders. I just can't see why it is doing this!
