Hello @alan12011
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I'm wondering here if they may be talking about the mondo patch or maybe a future release. Let's try a mondo patch to see if we're able to get it running through that. I'll leave a link down below so that we're able to try.

Once you've tried downloading and installing the Mondo patch see if we're able to get the investment register working a bit faster.
Thanks,
Quicken Francisco
