I guess the answer is: you bought models that were suspended due to some infringement (usually "copyright"). Nobody is guilty. Just don't trust any marketplace. If you BUYING or even getting free some important information or digital product on Internet, the best is to download it to your computer or private cloud storage. Trusting your files to the CGtrader is bad idea.
there was no copyright infringement , they were original designs and I have downloaded them but I've lost one of them
