Excel ran out of resources

Hi Kidd

thanks for your inputs, the file was working good earlier, the issue started when I changed the regional settings. 

1. I set the calculation function to manual, but still the problem persists.
2. there are no circular references
3. there is no spill issues now 

I am seeing only Cal! issues, when I try to change the formula it is working good, but when I reopen the file I am getting the same error message

can you pls help me with the process how to roll back to earlier version and check.

Regards

Ramesh
