There really is no way to help you with that amount of information, so I'll ask for some basic information regarding the issue.
OS?
CPU?
How did you install the game?
At what point does it give that message?
Can you provide a screenshot of that message?
If it is for the launcher:
It depends how big the difference is, but you will likely be able to deposit a substantial amount of the meseta -- but you will be disconnected if you try to deposit more than the server thinks you have.
