basically, logged in today on my pc, got error ‘no version information received’, un-installed and reinstalled unreal, this error did not vanish to my surprise, in doing this it caused my version of unreal to not register and I am unable to update unreal to any version. to top it all, decided to do a system restore to resolve this issue which was not present 2 days before, doing this did not get rid of the error, but doing this also got my 4.4.3 version back but every time I launch the version nothing happens, no error, no engine launch, need help.
I will close this thread because it has already been asked: Error! No Version Information Received - Getting Started & Setup - Epic Developer Community Forums 
It seems like epic games has some server problems.
