Expired_access_token when loading source from Dropbox

Greetings!
I’m writing C# .NET code to convert from XPS to .txt. I’m getting the following error:
“Exception when calling ConvertApi: DropBox Storage exception: expired_access_token/”

I checked Dropbox settings to see if I needed to authorize my app on that end, but it doesn’t look like that’s an option. Any ideas, friends?

Kindest,
katie

Please double check that you have configured Dropbox storage successfully with GroupDocs Cloud APIs.
