R30.10 is so slow for me it's unusable

gs377

30.10 just installed for me. I assume I was on 30.09 last week and everything seemed ok.
Clicking to download transactions - 43 seconds to prompt for my vault password.
Actual transaction downloads - 12 minutes 30 seconds.
Selecting an item in the downloaded transactions - 4-5 seconds.
Accepting a downloaded transaction into the register - 9-12 seconds.

How can I revert back to 30.09?

To revert to an earlier release, I suggest you perform a clean uninstall, install while disconnected from the internet, update by applying the appropriate Mondo Patch, and restoring a data file saved prior to updating from the earlier patch release.  If you haven’t already, you may want to review: https://www.quicken.com/support/using-qcleanui-uninstall-quicken. To update Quicken, I recommend you download and apply the appropriate Mondo Patch:  http://www.quicknperlwiz.com/quickenpatches.html

To prevent Quicken from applying an update without your approval, I suggest you set Windows UAC settings appropriately (choose default or always notify).

Before reinstalling, try just installing the Mondo Patch as it overwrites and damaged files. If it still is no good, then a clean reinstall may be best.
