I have installed Plus Live on my new computer (Windows 7) for a few weeks and there has been no problem at all until today I restart my computer.
Messenger Plus Live disappears!!!
I try to uninstall and re-install but it doesn't help at all....

I have read the thread posted on top but I haven't installed any of the applications on the list...

The only 3 softwares I installed the night before were:
Maxthon Browser (http://www.maxthon.com/)
Real Player
ImTOO MPEG Encoder Ultimate

I guess these 3 softwares will not crash with Messenger Plus Live...
But now it disappears!!!!

Please kindly help me to solve this problem.
Thank you very much!!!!!

Post a screenshot of your installed programs list, that may help us to find the issue.

Thank you very much for your reply.
Please find my installed program list as below.

I just tried to uninstall Maxthon Browser.
And Messenger Plus Live reappears again after restarting computer!!!

That means I can't install Maxthon Browser?
Any settings I can make during installation so that they won't crash together?

Maxthon is/was essentially IE in a pretty dress. There was a browser called Avant which may be a suitable replacement if Maxthon is the cause. Otherwise, I would choose a more mainstream browser.
