For the key pair you generated, did you create this in GoAnywhere OpenPGP Studio or another application?
If you did not use OpenPGP Studio to create it, you will need to include the key pair in your current key store.
If you did create the key pair and are currently pointing to the keystore location with where it resides, then please confirm with your trading partner that they are infact using your provided public key to encrypt their files.
Thanks - Jon
Here is a great video that explains how OpenPGP Studio works that is worth the watch.http://www.youtube.com/watch?v=brIgd--K-hM
