If I hit the Build the PCB button, it shows the Verify the package window. The window is empty, and If I hit the Build PCB, it shows error : There is no symbol. I have no idea where the problemm is, last week I Have build the PCB, and now for some reason I can not. Any ideas what happend?
Have you assigned packages to all the symbols in the schematic?
Noting your post about "Custom Attribute":

have you accidentally deleted the
package
attribute inProperties > Part Attributes ?
Can you post a copy or an example of a schematic that shows this problem?
