Does anybody else experience issues with Truecrypt 7.1a?

It displays

  X:\ is not accessible.
  Incorrect function.

and the Computer Manager displays the drive with the RAW type.

- Even though the filesystem is intact (tested on another Windows 8.1 computer) and

- chkdsk showing NO errors (yes that's right: it even shows the filesystem as being NTFS).

Aside from that my UI/UX experience with Windows 10 is great and I'm really happy. The above thing is a bummer though.
