Thank you for fixing the corrupt file. Can I ask what caused the file to be corrupted? And what can I do myself if it ever happened again? Thanks again for your help.
Open the aia with 7zip, go to screen1 bky file open it . Where every component started with title but in AI community it should be field, so i copied down all into a word file and used replace option from title to field , then saved the file and re uploaded the aia and tested it , found working .
