rjkrainak,
Thank you for your question regarding converting AXT files.
This is just a shot from the hip, but I'm curious if you've got a hard coded path in your AXT file that needs to be fixed up. If the error message all refer to a directory and a file that isn't in that directory (or the directory simply doesn't exist), then I'm sure that is the case.
If that doesn't help, could you post a sample of an entire error message? (error, message, file it refers to, etc.) That'll give us more info to work with.
