source control - git workaround?

I would suggest not bothering with the source control integration. We are using a tool that is supported and the integration didn't work well for having users working concurrently on our project. We manage the source control files outside of Test Complete and it works just fine. We've done it for months with multiple users. Take a look here: http://support.smartbear.com/viewarticle/56603/ you'll need to understand which files contain some of the project and suite meta data. For example to add a script you need to also update the script.Tc.script file. Once you've got that down its quite straightforward. Hope this helps.
