For those of you with APCC Pro and "Check for updates" is not working, please try this version (I'll post an APCC Standard version later if this works):

http://www.apastrosoftware.com/apcc_download/APCC_Pro_Setup_1.8.8.15.exe

If you still get a "blank" update version, please post your APCC log file here, or email it to me directly (groups3 at gralak dot com).
