Think I'm having an Import Issue.
I'm transferring all my products from one store (1.3.9a) to my new store (1.5.1). Download from original store goes fine. I upload the CSV to the new store via EP4, which also goes ok. It's a large file, so I split it. Ends up splitting into 5 files. When I IMPORT the first of the split files, it appears to be running, but then goes from the EP4 screen to a blank screen. I let it run for a while, just in case it is still working in the background, but nothing ever happens.

Anyone have any ideas?
