I added thet test for mt 3.8 forum.

Code:
Starting translation test for Google API v2
Test result: { "error": { "errors": [ { "domain": "usageLimits", "reason": "dailyLimitExceeded", "message": "Daily Limit Exceeded" } ], "code": 403, "message": "Daily Limit Exceeded" } } 
Test error: 
Connection time (ms): 154.723144531
is the response, but on my stats page for the v2 key it shows many requests, but no character useage?
