Screen hangs and Path Error

Import started but the screen is not responsive since. I cannot do anything even after restarting the server and deleting and installing the plugin again. The screen is totally unresponsive.

Also I was getting an error as unable to copy content from certain path to the wordpress directory. I think it was because of the ‘\’ as windows uses ‘/’ this and my images were stored before in linux.
How can I change the path name so as the plugin can import it to the directory?

I will post the error once the screen becomes responsive.
