Look i am not sure but generally internal errors come when your resources to equip the tool is less for example ram , processor speed , available space ..still i am not sure about this error just a rough guess might help you...good luck.
And even better if you raise a customer service request to altera, on mysupport. They will give you the correct remedy within 2 days- Mark as New

i would try a newer version, i don't think it's something specific to your design if it's happening when you're trying to program the parts
