If you are able to successfully sign into aCloud but you receive this error, then it means that your aCloud account does not have permission to access this product.
One of your organisations aCloud administrators will need to do the following:
Log into the aCloud website
Navigate to the Members section by pressing the person icon in the top right
Find the user which requires their permissions updated and press the ellipsis button on their profile and select the Manage Roles option
Under the Access Document option, give the user User with Client Access
Another option to try is to set the authentication credentials for accessing Access Document in Dimensions as follows:
Ribbon style menu:
Select System from the main menu
Select User Records
Scroll the list of users to locate the user unable to connect to Access Document
Click Options
Click Set ADM User
Enter the user's current Workspace email address in User Name and their current Workspace password.
Click OK
Module Menus/Classic style menu:
Select System Control from the navigation bar
Select Users, User Records
Follow from step 3 above.
