Ok point well taken regarding not closing windows properly and the computer crashes while LW is still open. However when I tried the Library window and select the incomplete folder, nothing came out??? How do I uninstall the current version of LW 4.10.5 Pro and install a later version of 4.10.9? I tried earlier to upgrade but I have to pay...I am a registered user of LW Pro and have made the payment before..do they still charge for upgrading?
