I don't think so. This is how it happened, to the best of my memory; ArchiCAD froze, I terminated the archicad process from task manager, then i reopened arhicad and it prompted me to recover my autosave file, after i recovered the file, a message came up saying the i was already signed into the plp file and will not be able to send or receive changes. Our plc file is saved on the network and we each have a plc copy on our local C: drives that we work from; if this is not to correct method for working on TW files, please let me know. I think a better question from me would be; have you ever had to recover an autosave file after a computer crash, and if so how did you go about it so that you could maintain a connection to the plp file?
Thank you for your input so far on my query.
