Problems in applying Service Pack 4.5.16.0

[User (Legacy)]

Hi Juan, 

I've applied the latest service pack 4.5.16.0 but it has introduced a bug 

when I zoom into a XY scatter chart. The lines are not refreshed and just 

seems to hang in the middle of the chart. 

How do I uninstall the service pack? or download a previous version 4.5.15.1 

to rollback the changes?
