I have a fellow System Admin who is able to create Report Subscriptions, but can't modify them, even subscriptions he created himself. He is just trying to modify the day and time that the reports are sent, but gets an error saying, "Subscription Unsuccessful. We couldn't set up your subscription. Try subscribing again. If you still can't subscribe, ask your Salesforce admin for help." He and I both have the same role and profile so I'm unclear why this is happening to him.

couple of things to check.. Assuming the User has the email address verified..
1. Is the Report for which subscription should be updated.. created by user or a different user?
2. Help check if the Locale of the system admin User as well as Locale of Running user of the Report is same. If different, you might be hit with the error.
3. Help check if the Folder access of the Report has the access granted to both of you and Folder Access is set as Read/write
