Hi Konstantin,
Thanks for the quick response.
I will look into getting a newer GA version.
Regarding the GA not available, is it relevant to the newer versions? Is
there a way to make sure the GA is available when running the freeze? when
it is not available it takes a lot of time to get a response back and it
causes the freeze to delay.
Best Regards,
Shelly
