Hi Josh,
Glad it worked for you. Verify if all the activities and resources work OK now, however. Some of the deletes may have been linked to the still existing course modules. If you find anything broken, download one of the old backups onto your machine, open it with an unzip facility, extract the file needed and re-upload it through the resource's / activity's file-picker. Might not be straightforward as Ken has explained above.
I just hope my own trying to help did not cause all these new problems.., :/
