Change mode of oa_update_mode from false to true

Hello,

I am having a problem related to the setting of the oa_update_mode from false to true: when I run, after P&R, DRC and LVS, the power analysis I get this error:

Firstly, I tried to change the mode in my P&R script but I still get this error. I look for a solution everywhere and actually I did not get very well what does it mean "Free the design from memory" and I should do too.

By the way, I got power results and I do not figure out if this error really affect my results.

Can someone help me?

Thank you in advance
