Microsoft now follows the same pattern as Apple with OS X: Windows version will now be always 10, and something else will tell the exact version. Just as Apple recently released El Capitan, Microsoft just released a new version, which seems to break FM 14.
I am at this time upgrading a test Windows 10 to version 1511... it's been running for quite a while . I will try once it's through.
I am afraid all this means a new version - 14v05 ? - will be needed from FMI. I am sure someone from FMI will chime in soon.
