Odd error messages

[Amaturus]

Some time ago I installed an English version of µTorrent. Very regularly, at the start and occasionally, lately, I get one of two error messages in the 'Status' column *in the language of my operating system* - not in English. One announces 'Wrong parameters' and the other says 'Invalid data'. Both of them cause a complete stop for the torrent involved and no attempt at all at recovery. Both of these happen in very specific circumstances: a) whenever I choose not to download parts of a torrent, and during the first 1 to 1.5% of the download. Never with a complete torrent, never past the first few parts of a download. Odd, no? Any ideas, anyone? (I'm thinking it's a C++ thing, but I'm not too familiar with the language).
