Hi hamcat, 

Let's perform some troubleshooting steps so you can load new pay run.

There are times that the browser stores frequently-accessed data, thus causing websites, like QuickBooks Online, to act weirdly. Let's try logging into your account using a private browser.

Here's how you can access it depending on the browser you're using:

• Google Chrome: press Ctrl + Shift + N
• Internet Explorer: press Ctrl + Shift + P
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Option + P

Once logged in, go back and try to load a new pay run again. If this works, it means that you need to clear your browser's cache so the system can start fresh. If you get the same result while using a private browser, I recommend switching to a different browser.

Feel free to post again if you have any other questions. I'll be around to help you.
