Recording malfunction

[mikaz]

I've recorded many meetings but now when watching a new recording it stops midway, I then start it again but it stops in one or two seconds. I can go forward on the recording but the same thing happens. The recording is there I just can't access it. It also is happening on older recordings that were previuosly ok. It's not a storage issue. My computer is pretty new.

Any ideas? Thanks:)
