Windows 8.1 update has killed cubase le5, urgent!!

Updated windows today to 8.1 and as a result Cubase LE5 no longer works. The ELC does not work

“soft e-licencer doesn’t have enough permissions to run properly. please run LCC to fix the problem.” when I go to do this, “If you wish to continue using the programme register now with steinberg free of charge to activate program. register now or cancel” the software IS already registered

It will not let me into the program as a result. I have tried going to a system restore but as windows has updated my old restore point has been lost. Any advice? Need it fixed by Thursday so any help would be appreciated, thanks

Did you check to see if your version of eLCC is the latest version?

So try doing a re-activation of the software then…?!
