Hello, I am a student and we are working with the GoogleAdwords api, using the PHP client library. After changing a lot of the pathing in the library, I was finally able to get the refresh token. However, now I am unable to run basic api calls like GetCampaigns, GetAdGroups, etc. Am I supposed to be changing all of this pathing inside the library? The current wall that I've hit is when I try to run GetCampaigns it can't open AdWordsSoapClient.php from the CampaignService.php on line 29, despite updating the path to include the location of the file on my computer.
