Picasa error after nvidia install

Hi
I installed the relevant NVIDA driver manually a while ago (There is aproblem with the one click solution One of the repositories arent found if I remember correctly)

And every thing works fine except picase. Every time I want to run Picasa I get the following error message after a rebopot


 /dev.nvidia0 or /dev/nvidiact1 are not accessable. 
Picasa will crash if these file are not accessable. 
To fix this, as root, please run: chmod 666 /dev/nvidiactl
and then restart this program 

Also I can never remmeber if the correct command is an ONE or a L Think it is an ELL! The capital letter
look at the attached pic if needed

It works but it is a bit of a pain to do it every time after a reboot what other solution can you suggest?
In windows I would add it to the autoexec.bat but in Suse I do not know!
thanks!
