Hi All,
I created a base male character, but wanted to import some shirts/clothing that are in FBX format. I keep getting this prompt to Decrypt Key File. I don't know what this is, so I can't get beyond here. Is this because I'm still using the trial version?

Any help would be great. Thanks in advance!

Use "Accessory" from the menu to bring garments into CC and then "Transfer Skin Weight" to convert them to *cloth*.
"Cloth, Hair, Acc" is to bring the dressed character back (which was originally exported out of CC for customization and dressing).
