Hi Ricky,
Thank you for posting your query in Microsoft community forums.
I understand that you are getting an error message “Casino component 'poker_lobby'_new is missing” while opening the poker sites and also get an error message that livecomm.exe has been suspended.
I would suggest you to answer the questions given below.
1) What is the browser that you are using to access poker site?
2) If it is Internet Explorer, are you using Desktop version or Modern UI version?
3) Is there any third party antivirus software installed in your computer?
Please post with the required information to help you.
For the error message “livecomm.exe has been suspended”
I would suggest you to run Microsoft safety scanner and check if the issue is fixed.
Download and run Microsoft Safety Scanner from the link to make sure you computer is not infected by virus:
http://www.microsoft.com/security/scanner/en-us/default.aspx
Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.
Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
