Camtasia 8.6.0 auto-saved (when I clicked "Save" after recording complete) to the trec format and then Camtasia crashed before I could publish to another file format. Now it won't open file in Camtasia - says unsupported or missing codec, in fact, Camtasia will not recognize any of my previously created files in trec format. I uninstalled/re-installed Camtasia but this did not resolve the issue. I also performed a repair and this also did not resolve the issue (was hoping it would find the codecs). Please help me understand what I need to do to open my trec files in Camtasia in order to edit and publish to other formats. I'm on Win7. Thanks.

Well, I went back and re-recorded a portion of the two-hour production I was working on and the only file format I can save to through either the "Save" or the "Publish" button in this version of Camtasia is trec which appears to be unsupported, or the install of Camtasia doesn't have the proper codecs to read it. Camtasia throws the same error as above when I actually try to open and edit a file with trec extension. It seems the best thing for me to do is to uninstall this version of Camtasia and re-install an older version of Camtasia and then try to record again as I have to get this project done today. Appreciate any feedback. Very frustrating! 

Now I am reading posts and seeing that many people are having issues with Camtasia 8.6.0 crashing in Win10 which is what is happening to me although primary issue is that trec format is not read in Camtasia 8.6.0 so there is no way to edit my files. I did find that videos under two minutes can be saved as .mp4s and other formats, but I am still unable to edit and still unable to avoid crashing. I am going to try to revert to an earlier version of Camtasia at this point.
