Hi aaphysio,
If you are currently having issues with accessing the payroll system after setting up your details and running a recent pay run this may be attributed to a browser issue. To fix this, I would encourage you to click here for troubleshoot steps that include trying a different browser.
After trying these steps if you find the issue continues, I would encourage you to reach out to our friendly support staff so we can check the setup of the account and assist further.
Thanks,
-Steven
