I have posted this many times but here it goes again:
You have to update the Flash player manually when using Maxthon
Here's How:
Update Flash Player first
Then go to My Computer, your hard drive
Under Windows find the file SysWOW64 click it
Find the file Macromed click it and the file Flash
Copy the latest file which is now NPSWF32 18.0.0.232.dll
Now you have to go into your program files and find the Maxthon program
Click on it, then click Core,
then Webkit,
then Npplugins
Paste the copied dll file and delete the old one
