Pointer to attribute Invalid Error was Fixed

Hi All,

 I was making the 2 layer PCB of Gesture Control.

- I went to generate my artwork only to find out I can't because there is a database error.

- I check dbdoctor.log and it says "Error in Attribute     Pointer to Void Invalid", 1 error could be fixed

- I do a database check (including regenerating DRC errors) and it reports that 2 errors were fixed, both referencing the same error message above.

- Sounds like I should be good to go, but when I try to generate the artwork again, I get the same error message and the cycle continues.

Can somebody suggest me how to resolve this Problem?

Thanks in Advance
