SAP Active Gloval Support got me running, here is what they had me do. It appears that MOPZ downloaded too many things (notable old SAINT/CRT packages). Removing them from the download directory and out of the EPS inbox got me past the point of failure.
First:
remove these packages from the EPS-Inbox using transaction SEPS
transaction(Goto -> Inbox):
SAPK-700Z1INCPMBPC
SAPK-750Z1INCPMBPC
SAPK-750Z2INCPMBPC
Second:
remove CPMBPC750.SAP from the download directory.
Lastly:
repeat the phase from the beginning
