Bought Websitex5 Evo 11 one week back in Brussels.

First installation successful, started building first web site yesterday, saved and tried to resume next day(today), but Website X5 Evolution 11 did not load , error message : Please reinstall the program. ("Could not load file or assembly 'CefSharp.dll' or one of tis dependencies. The specified module could not be found.")

I just tried to re-install, I  reached registration/activation, input the license key and original mail address, and at completion asked to launch, same problem. Tried a second time, same problem. 

Please advise as I do need to complete that website I had started as linked to an event due in the short term. 

Thanks
