Building off of Glenn, what you can also do is also make sure within the "Save to Repository" task, you click the green "Edit Profile" and then select the blue "Verify and update", and make sure it checks out. Otherwise, perhaps credentials/rights may have changed resulting in what you may be seeing now. And if there really is an issue, the event logs will note it.
A few other options you can try is
a) creating a new simple forms business process
b) use different credentials within your profile in "Save to Repository"
c) save to different repositories
