The first issue “Exception…” can happen because of file sharing issues, or permissions, that I know of. Does this happen also when you access a local file? I’d very much like to work with you to solve this issue. Later this week, we’ll probably try to release a version with some more diagnostics output for this kind of situation.
The second issue may not be an issue as such. AxCrypt 2 uses a more robust method for the automatic re-encryption, which sometimes means you as the user has to tell AxCrypt to do it. You’ll see this by the “broom” icon becoming red. This indicates there’s something in need of “clean up”, i.e. re-encryption.
