Hello, the import demo content process remain always at 50%.

I try to refresh page during the process and repeat import: OK, DONE.

BUT i have 2 times the same products and categories, and revolution sliders…..

So i delete file and database and install all again.

I repeat the process and now is again on 50%….

How i can resolve? if i stop the process i will have problems? please let me know, i dont want install all again.
