Pi WebParts 2013 not showing

Hello,

I have a VM running Windows Server 2008 R2 with SP1, deployed AD and SharePoint 2013 with no errors and all and proceeded to install Pi WebParts 2013.

Pi WebParts 2013 installed just fine and I deployed it in my site collection and activated it. I can see the list of WebParts if I click on Edit and browse what's available.

Unfortunately if I try and select anything.. like ActiveView or BatchTable, after clicking on Add the page just refreshes and I'm left with nothing. No changes to the page.

Anyone know what I could be doing wrong?

Edit: Sometimes it would show a "Sorry, this site hasn't been shared with you." error.

Thank you in advance!

Regards,

Isamu
