How to deactivate licence when you can't run Trados at all?

Question

I've just installed Service Release 3 for SDL Trados Studio 2015 (I wish I hadn't!) and now I can't run Trados at all. It says "There is a problem with the installation. Studio cannot be run. If the problem persists you will need to re-install Studio". 
 My problem is I now can't deactivate my license, neither online or offline, because the app can't be run, and I don't know how to contact SDL so they can help with this. 
 Can anyone help? This is obviously quite urgent. 
 Thanks!

Hello Rosa, 
 
First of all I would not bother deactivating the licence. It's not necessary unless you rebuild your computer or intend to reinstall on a new machine. So just ignore that message. 
 
But if you really want to do this then you can contact support using this link:

Just fill in the form and submit it. Make sure your email address is entered correctly or nobody will be able to get back in touch with you.
