1. i keep getting the following error when trying to add a video ad in the sandbox:

<soapenv:Body><soapenv:Fault> <faultcode>soapenv:Server.userException</faultcode> <faultstring>One or more input elements failed validation.</ faultstring> <detail> <ns1:fault xmlns:ns1="https://adwords.google.com/api/adwords/ v11"> <ns1:code>122</ns1:code> <ns1:message>One or more input elements failed validation.</ ns1:message> <ns1:errors> <ns1:index>0</ns1:index> <ns1:code>4</ns1:code> <ns1:isExemptable>false</ns1:isExemptable> <ns1:detail>The specified user not allowed to create a video ad.</ns1:detail> </ns1:errors> </ns1:fault> </detail>

the request:

<soap:Body> <addAds xmlns="https://adwords.google.com/api/adwords/v11"> <ads xsi:type="VideoAd"> <adGroupId>26227</adGroupId> <adType>VideoAd</adType> <destinationUrl>http://akatracking.esearchvision.com</destinationUrl> <disapproved>false</disapproved> <displayUrl>subaccount-360.com</displayUrl> <exemptionRequest xsi:nil="true" /> <id>0</id> <image> <data>/9j/4AAQSkZGp6u4rH/2QA=...(Truncated)</data> <imageUrl xsi:nil="true" /> <mimeType xsi:nil="true" /> <name>doc_363_3112071159</name> <thumbnailUrl xsi:nil="true" /> </image> <name>Title-VideoAd-3</name> <video> <videoId>1110216958464537981</videoId> </video> </ads> </addAds> </soap:Body>
