Potential PC problems

[Ratel]

To all my opponents. I could potentially have a problem with my PC. During the last few days I have received files form opponents and when opening, it asked me for the password of another game than the one intended. I first thought that my opponents must have sent me the wrong files by accident as this has happened before. However, I found that it happened with three of my opponents all at the same time!! Then I also received e-mails back from 2 or 3 of my other opponents, saying that I have sent them the wrong files even though I am pretty sure that I didn't. Even if I did I don't believe that I would have done it as many times and to as many opponents all at the same time.
That makes me think that my PC is maybe busy stuffing around.
In one case I got a file from a player (Gila), and when opening it asks me for the password of the Slovak player. I e-mailed Gila but he says that he doesn't even have a game going against any player that is playing as the Slovaks. Neither do I.
Could it be that my PC is changing files by random?
So for those that I am playing against. It seems that it does work after the second attempt to send the files, either way. Can I ask that you have a bit of patience while we play. We can still play, but it could be that we have to send the same turn through more than once every now and then. Luckily I am nearly done with most of these games that I find the problems on. :conf:
Anybody that maybe has some advice on how to fix this?
