1. Go to the Test Plan module and select the test's scripts. Check if the script appears in the Test Script tab.
2. If you get an error stating that the script wasn't uploaded correctly, delete the problematic scripts, upload them again, and fix the link to the scripts in the Performance Test Designer window.
3. Try to run the test again.

The problem can also happen in a version control enabled project:

- Examine the scripts defined in the test you're trying to run.
- If a script was uploaded using VuGen to a version control enabled project, it is not immediately checked-in, so a checked-in version of it does not yet exist. This will cause tests using that script to fail. To resolve this issue, check-in the scripts.
