i have no problem downloading other trainers not even the ealier versions of the trainer for resident evil 6 and rev. but the newest ones it cant.. it says that it cannot download it cause the sourcefile cannot be found and I need to contact its systemadmin. ......so it is nothing to do with my firewall etc.
Sorry but I just tested the top two trainers and they download fine via FireFox.
