[Tool] Advance Trainer deleting itself when run

Advance Trainer was the only trainer editor that doesn't crash when I load a ROM, it used to work great, but it randomly started deleting itself when I run it. Theres no crash message or anything it just closes and is gone.
I know its not my antivirus cause I disabled it and its not a problem with my ROM because it happens usually even before I load one.
I can't work on my hack without a trainer editor ):
please help

Have you tried having a look at HexManiac Advance?
I think you can look at and change the trainers pokes in that.

use HexManiacAdvance as it contains a far more complete/up to date trainer editor.

Thank you so much
