FAQ for registration and payment | onlinechemlabs

We welcome your questions and would like to hear suggestions on ways we can improve the quality of your virtual laboratory experience. Here are some of the most frequent questions that we receive about our labs.


When I click try to register or login, I see an hourglass, and then only a blank page.

(1) You may be using a non-standard operating system or browser. Internet Explorer 7 and above, Firefox, Chrome, and Safari all work with Silverlight. Linux systems, and other non-standard browsers may not be compatible.
(2) Your version of Silverlight might be corrupt or out-of-date. Try uninstalling and then reinstalling Silverlight.

I did not receive a verification email.

(1) Check if your email address is correctly entered on your My Account page
(2) Look for the verification email in your junk mail folder
(3) Check if your email client is set to reject email from addresses not in your contact list
(4) Note that you cannot perform this registration process from within Blackboard.

After correcting any of the above, please try the verification step again; it should work.

I am not able to make a payment on Paypal.

(1) Do not open the lab page within Blackboard, because the connection to Paypal will not work. Open a separate browser window directly from your desktop and try again.
(2) Use the most reliable browsers for this one-time process (IE7, 8, 9, or Firefox).
(3) Reboot your computer, and try again with no other applications open. Some open applications such as Facebook or mail/messaging might interfere with the Paypal interface.
(4) If all else fails, switch to a different computer to make your payment. This is a process that you only need to do once per course.

I have logged in, but do not see a full list of labs or the Open Lab button on the My Labs page.

If you do not see the Open Lab button, you probably need to increase the resolution of your computer screen. We recommend a minimum screen resolution setting of 1024x768.

How can I change my computer screen resolution?

The procedure depends upon your computer and operating system. On a PC running Windows 7, you can right-click anywhere on the desktop and then select Screen Resolution. For other PC operating systems, right-click anywhere on the desktop; select Properties>>Settings>>Screen Resolution. On a Mac, open the Apple menu and select System Preferences>>Screen resolution.
