Thanks for your post and welcome to the forums. It's great having you on board with us in the Community.
I'm sorry to hear you're having an issue with creating a My VM account. We're aware that some people are having an issue with this and there are a few things I need to check with you.
Can you please ensure you are following ALL of the below criteria when choosing a password.
• Between 8-10 characters.
• Must start with a letter.
• Contain at least one number.
• No special characters.
If you are 100% certain that the above requirements are all being met then can you try some different password variations? This is because we've had reports of customers being able to proceed when doing this and it's mainly because some choices are too guessable to be allowed.
You should also try registering through the app or through another browser to see if this helps.
Should this not work, pop back here and let us know. We will then be able to raise this with our IT teams to manually create the ID for you.
Keep us posted.
