Creative issues in Studio
Local Connect preview connection has failed.
If your DoubleClick Studio Local Connect component functions in Flash but doesn’t preview correctly in a web page, you might have opened Local Connect in multiple browsers.
For creatives that use Local Connect, you can't open the same preview page in multiple browsers at the same time. Local connection works by system and not by browser, so make sure you preview in one browser only. This error can occur on both Studio test pages and live sites.
