Hello dear friends . i have a external hdd full of .grod extension files . while reading on the internet i got really confused . i know i don't have a t1 at the end of the personal ID so it makes it a online encryption . i tried the emisoft software it's always stuck at starting . i tried the encrypted and original technique by re downloading the exact same software i had with it's encrypted version and i got this message " Invalid file pair; file encrypted by newer version of STOP Djvu "
thank you for your help
