Kr firmware updated installed but....

Hi all. I have today updated my Kr camera with firmware 1.13. All is working fine until I attach my Tamron 70mm-300mm lens. On the screen there is the flashing "F--". I have found this website (need to translate as it is in French);

Pentax optio optiowp optiox k-m km *istd *istds ist istds dsmobile 600 versacam pocketjet photo browser 3 photo laboratory 3 hoya ricoh

I thought this can just be fixed by installing an older firmware. No this does not work! How can I fix this as I need my camera ready for Silverstone!

Any help would be much appreciated!

The lens has an aperture ring.

Make sure it's set to 'A'.

... or no aperture transmission (i.e, is an old K/M glass), in which was you have to enable the use of the aperture ring (under the Advanced menu).

Enable aperture ring in the menu (I think its at the very end of the menu), and make sure the lens contacts as well as the camera mount are clean.
If the lens has an aperture ring (similar to focus and zoom rings, but with f- numbers on it), there is probably a button on it and you can push the button and set the lens to "A", this will give you more automation.
