I had this unusual issue recently. Few of my keyword test are now unavailable and I am not sure what the issues is. I could see .tcKDTest files for those test however TestComplete says it is unavailable. Can someone please advise what can I do to sort this out ?
*Please refer to the screenshot for the issue
And again, make sure your entire project is backed up!
The .pjs or .mds files have references to how you project is structured. You need to update the path references so that it points to the correct file (search for your old filename e.g. Test3_3016.tcKDTest in the text file).
Once you have updated these references, open the project in TestComplete, and hopefully you should see everything back to normal
