Hi Guys and Gals

I used to have windows 10 Insider Preview running on a separate partition on my laptop, until recently.
I had a choice at boot-up as to which operating system I wanted, either the Insider or my regular Windows 10 Pro, then, all of a sudden the choices were not there. I just couldn't get into the Insider system.
I thought that if I deleted the system I would be able to download a fresh installation, but, I just can't find an installation that will load. I keep getting the error message "winload.exe has expired" and there is nothing I can do to get my Insider programme to load and work.
Please, please, has anybody got any ideas as to what I can do next, I still want to be a member of the Insider programme, but can't download a loadable replacement.

Waiting with fingers crossed
