Not sure what is incorrect but in answer to the two questions I see posted.
One is the typo I mentioned prior. UPS v UPC human error by someone.
The other
1062 Duplicate entry 'EASYPOPULATE_CONFIG_TEMP_DIR' for key 2
Means you have already inserted the selected sql files data during a prior operation and therefore the "error" should be ignored.
The first error will cause db problems though so the file needs to be edited to repair the defective code.
As to .4 being the one to use... several EZ Pops in downloads area are completely 100% stable for years. .4 however has the least amount of functionality which is why it is not on the downloads areas anymore.
While all are basically the same U may find that more recent versions provide a better admin interface and inventory management ability.
Really this thread should be restarted with a more recent versions name but I digress. Let us know if you are still having issue with your ez pop install
