can't open FP 5 data base in FP 11
Had a computer crash, have old database file in FP 5 or FP 6 when try to open with FP11 get the message
The summarized field's data type must be number , date,time or timestamp.
Have down loaded FP 6 and coverted to FP6 but this is only 30 day trial version when go to buy can only buy FP11. Can't load old FP5 as classic installer will not load on new mac.
Use FileMaker 6 to perform a recover of the file, then attempt conversion of the recovered copy. It's possible that your original file is damaged.
