Hi lydincamilleri!
One solution here would be to setup the 'On error' parameter for your tests to 'Stop and rerun current item'. This way whenever an error occurs TestComplete will rerun any tests that fail. You can even specify how many times you would like to rerun a failed test.
This can be altered from the Execution plan for each test, or within the Project properties as well.

Here is our document that outlines controlling your test flow within TC;

I hope this helps!
