That may be true, but the problem lies with their software, not with your machine. Therefore, they will be able to go farther than we will to fix it. If you are having problems that they cannot fix, it is likely a bug in the game.
If the software does not support vista, you will have problems.
Have you tried compatibility mode?
Because this is an issue with beta
software, you really should NOT be surprised if the software does not work. It is marked as beta because the developer knows there are bugs left in the software, bugs great enough to prevent a general RTM release.
Because this problem is caused by the Nittolegends software, you really should post this issue in thier forum
, as most of the helpers here do not have experience with the program, while those at the Nittolegends.com forums do have experience with the program.
If they cannot fix it there, then the only thing to do is wait until a stable version of the program is released.
As you can see here, there is quite a long critical bug list for this game: http://www.nittolegends.com/community/forumdisplay.php?f=45
Have a nice day,
