LOTW

Hola foro ,soy EB3EAW y tengo un problema de instalación con lotw desde que cambien el disco duro y he hecho mil cosas para poder instalar para ver si alguien me puede echar un cable os describo el error :

I am trying to install the certificate I have after having formatted my computer, but every time I try I get this error "Callsign Certificate or Certificate Request for callsign serial not found EB3EAW 328772" and can not continue. As I try to install the tqslconfig.tbk file, the certificate loaded fine, but when I close the program and I open, I get in "callsing certificate" next to my name indicative letter A - B and if I give to see what he says makes me "Replaced" and can not continue. What I can do? saludos muy cordiales 73 Miguel eb3eaw
