Missing Media Images after Migrating from WordPress.com

I recently migrated my WordPress.com account to a new www.remarpro.com account. I’ve exported the XML file and imported it, however, I am having issues with the Import Attachments step. I check the “Download and import file attachments” box and click Submit, but each time, it only adds one Media item at a time. Has anyone else had this issue before? How do I solve it besides manually uploading my Media items?

Thanks in advance
