Hello all - thanks in advance for any help you can give. I am trying to recover a very substantial piece of work urgently. I have coded a number of PDFs in a project called p4 (attached). It will not open. I will paste the error message I get below. I have tried to recover the project by opening the recovery file - this does not work (NVivo crashes/closes). I downloaded the dummy project file for recovery. I got a message to say that recovery had been successful, but then NVivo crashes/closes again. Once again, thanks for any assistance or insight that anyone can offer. Brett - Error message when attempting to open project: Error Message: An item with the same key has already been added.

Good afternoon, I'm not sure if this is an NVivo issue or a local server issue. My local IT support are completely dumbfounded by the issue. I have been accessing Nvivo remotely via a webdrive/VPN functionality. I am able to save to the secure and shared drives any file format except .nvp. Is this a problem anyone else has encountered? Many thanks Mathew
