Able 5 store to 7.0.4 dataport error

[jmestep]

I'm importing orders from an Able 5 store into a 7.0.4 store that was upgraded from 7.0.3 before going live. I had done an original import a few months ago of about 70,000 orders. I'm redoing the whole user and order import right before going live to catch user password, etc changes.
The dataport has stuck twice on orders when it hits about 77,265 orders which is about 20,000 orders short.
I'll upload an image of the error message. I've changed my max request length in the web.config to see if that helps and I'm trying again.
I did it yesterday from my own computer and left it running all night and got that error this morning. So today I am doing it from the server the old site is on- installed the dataport there.

I changed the max request length in the web.config to be larger than 4096 and all imported now.
