Hi Johny,
What version of DevTest are you using?
I think your environment seems to have a problem by your sentence "Then opened CVS. But I see only blank page."
But normally, you can see the test(or suite) reports like these steps:
1. Login to DevTest Portal
2. Select Reporting->Test at the left menu bar
3. New tab apprear and you can see the several report names
4. Select one of them (example. "Suite execution detail") and you can see the suite result
But if you have problems by following these steps upper, then please open a support case with your DevTest Version.
Thank you,
