Hey @cooksteve09,
Welcome to the community and thanks for taking the time to post your issue on the forums.
Can you confirm the password you're using meets this criteria;
8-10 characters
Starts with a letter
Includes at least one number
No special characters
If so, can you try a new browser for me? This has worked for me in the past to solve this. The last thing to try if the new browser doesn't work, try clearing all cache/cookies, auto fill passwords and browsing history.
Regards,
