Hi Michael,
If the network problem just started without doing any software updates, then a power reset for your router and any switches that are part of your home network, should fix this upload problem. If the problem persists after the power reset, then I suggest unchecking the Passive Connection check box in the File Uploader's Connections dialog. This is below the FTP Server Name or Address field. If you are still having problems with Photo Mechanic FTP uploads then I suggest you contact our support department - support@camerabits.com.
Best regards,
