Cause
When a VSM or a test case interacts with server, the responses are saved to a response document so the information is available later.
The response documents are created and maintained automatically. They are saved as files with a test case or VSM file name and an .rsp extension.
If for some reason this rsp file is corrupted, you may be unable to open a test case or a VSM.
Environment
Resolution
Delete the .rsp file related to a VSM or a test case that you are trying to open.
