Unable to upload designs to the Design Share.

Hello, guys

I have a couple of designs on the Lotus E21 and Audi R18 I’d like to upload to the design share interface to make a few quid, but I’ve had an issue. On the E21 with my Red Bull and Mercedes replica liveries and my three 2014 Audi LM designs for the R18 it says something like “Issue uploading your design. Please try again later”. When I have “Tried again later” after days and even weeks, I get the exact same message.

Any help?
