Laurent Matheo, Can you please get someone to help with this?
I tried to restart sandbox, no use;
I tried to reset password for just the integration services, no use;
I tried to reset password for all 3 IS accounts, no use;
Now its asking for "You must accept the License Agreement to continue using Integration Service.";
All: The restart of Integration Studio service by BMC seems to have resolved this issue; No further action required on this; Thx.
