Reply to Recovering unfinished Traktor Recordings

Hi all, I just wanted to ask for a little technical advice on an issue I've just had recently.

Yesterday, I was finishing up a set on Traktor with the built-in mix recorder active in the background. As I'd finished and went to quit, I realised that the mix recorder was still recording (which is something I'm normally aware of stopping before I exit). As a result, Traktor hung on "Flushing Background Tasks" which in turn, rendered the WAV file unreadable by just about every media player I've tried.

My question is, would I be able to repair the file by "tying up the loose ends" where the mix did not finish recording successfully. I didn't know whether there was an app of some sorts that would allow me to trim the end data of the file where it had become corrupt. It's a good solid 450mb file which leads me to believe that there's enough usable data in the file.

Luckily, it was a long set and Traktor had already split up the files automatically, all of which work perfectly, so I'm only trying to save the last hour of the set (typically, my personal favourite section!)

Any advice would be really appreciated.
