UnitCapture/UnitPlay no longer working?

[khaosmatical 237]

About maybe 3 months ago or so the UnitCapture and Play function worked beautifully, I had no problems with it and learnt to do it from 'TheJServer's video (

). But now now I try to do it the same way it simply does not work? I mean I get all the coordinates in proper place, everything is named correctly but when I hit play it does not play the captured footage?

Has the system been updated that I am unaware of?

Thanks.
