I just installed Massive Assault. When I click on the desktop icon that says Massive Assault Game Menu I just get a screen that says Matrix Games. When I try to start it from the program menu, I get a message that says that I am missing files. There was also no place to enter the registration number. Could that be the problem? Does anyone have any idea how to get this game to run?
Thanks

you can try to start massive assault from the place where it has been installed.
If it does not help, please visit our support page at www.massiveassault.com/support.php
or just send ma.log and DxDiag.txt files to me at vadim@wargaming.net

Please, try to do the following:
a) Run Windows Explorer
b) Browse to the folder where Massive Assault was installed (there must be "ma.exe" file)
c) doubleclick on this "ma.exe" file

If the game doesn't run or crashes or gives any messages, then, please, email the ma.log file (which can be found in the same folder) to
vadim@wargaming.net

Thank you for your patience and understanding
