Hi japjap, Unfortunately I cannot tell u if it is OK just to remove those parameters. There are at least 2 reasons: 1) it is not right to manipulate with things of "unknown nature" . I still trying to find out what that parameter mean despite the package is working now fine for arround 4 days. 2) I read here and in other places that removing those from shortcuts created by Nero wount help because they will reappear and all other probs remain the same. The only thing I mentioned at the very beginning of the thread that I created own shortcuts from programs bases or just could ran them from there and in such situation the mysterious parameter(s) are not passed to progs. Take care
