I am very confused. I have had several trainers from CH with NO problems ever until NOW. I have tried all 3 trainers with NO luck. F key activated and NUM Locks activated. Trainers loads, says its activate but when trying to use number keys NOTHING happens on any of the 3 trainers. YES I have deactivated all AV, Firewall, Malware etc and still the trainer won't kick in even though it says the trainers is activate. NOW WHAT TO DO? I have read and re-read the trainer troubleshooting guide and tried to follow what may be the problem but still NO luck. What am I missing? What can I do to activate one of the trainers to work. NEED a trainer to work badly. Stuck in Lost Temple with very intense fight and not progressing. Any help would be greatly appreciated. Please respond.
