Upgrade to Slideric Pro

[tgav]

So I currently have the Free version of Slideric on my index page. I am trying to upgrade to the pro version but having a lot of trouble with it. When i try to upload the zip file in the add new module page i get an error message saying it cant upload file may be corrupted. I already tried downloading the zip again and trying the new one and that did no good. But even if i did get the zip uploaded i wouldn't know where to go from there. Any help would be much appreciated.

 

Thanks
