You can only have so many trainers saved for offline use during a 7 day period. Not just THIS particular trainer. Not sure if Deathrow or 0x90 might be able to tell you which trainers you currently have configured for offline use.
Any chance i can get a reset so i can use the trainer?
I personally cannot do it. You can try kevin@cheathappens.com.
I email Kevin he said he dosent have the authority to reset the trainers.
