I inserted EPL club logos into FM and for awhile it worked, as in the small logos in the EPL table as well as the bigger logos at the squad page. but then, i messed about, trying to put on kits but the kits dont appear!, my bigger logos disappear...the smaller ones are around but the bigger ones are gone...odd....anyone got any ideas? i checked my folder and it says that the "Normal" sized logos are still there...weird
