## The most common questions

Most of what people write in about is answered below. If yours isn’t here, the form at the bottom of this page comes straight to us.

### Having trouble logging in?

Your username is the email address you signed up with, not a separate name you chose.

Forgot password? [Reset it here](https://my.3dmusclelab.com/login/?action=lost) using that email address.

If you get an invalid email error, it usually means a typo, or that you signed up with a different address than the one you're trying. Worth checking any other addresses you use.

**Getting logged out repeatedly?** That's almost always a stale browser cache. [Refreshyourcache.com](https://www.refreshyourcache.com/en/home/) has clear instructions for every browser.

### Can't find your course?

First, check whether you're actually logged in. Look at the top right of this page.

If it says **Login**, you're not. [Log in here](https://my.3dmusclelab.com/login/) and you'll land on your courses.

If it says **Logout**, you're already in. Click **Go To Course** and you're there.

### Videos not playing properly?

Video is delivered through Vimeo, which has infrastructure worldwide, so playback problems are usually local. Check your connection first, then make sure your browser is up to date. Those two account for nearly everything we see.

Lessons stream rather than download. That keeps your access working across every device you use without you having to manage files, and it means the library stays current as material is updated.

If it's still not behaving after checking both, write to us below and tell us which lesson and which browser.

### How do I cancel my subscription?

Log in, and you'll land on your course outline. At the bottom of that page, click **Account Details**. Under the **Subscription** heading, cancel the subscription.

That stops the billing and leaves your account intact, so your history and any other access you hold stay where they are. Closing the account is a separate, permanent action further down the same page, and it isn't what you want if you're only stopping payments.
