IE 9 issue with Multiple File Upload Plug-in

IE 9 issue with Multiple File Upload Plug-in

Browser is IE  9.0.8112.16421
jQuery Multiple File Upload Plugin version is  v1.48 (2013-02-19) (The latest I assume)

One of my users is having issues getting the multiple attachments to show up when using this browser version. Is there any known issues with this plug in and IE9 or any idea how to possibly work around this? 

The use of the plug-in was very simple. I just added a "multiple" entry to the input tag and listed the allowed file types and it worked just fine in IE 11/Firefox

Any help would be greatly appreciated, thanks!
