VisuakBasic error

[ollegaard]

I keep getting:
Unknown Error: Microsoft.VisualBasic
at Microsoft.VisualBasic.CompilerServices.DoubleType.Parse(String Value, NumberFormatInfo NumberFormat)
at Microsoft.VisualBasic.CompilerServices.IntegerType.FromString(String Value)
at Microsoft.VisualBasic.CompilerServices.IntegerType.FromObject(Object Value)

at System.Windows.Forms.Timer.OnTick(EventArgs e)
at System.Windows.Forms.Timer.Callback(IntPtr hWnd, Int32 msg, IntPtr idEvent, IntPtr dwTime)The currency separator information specified in the NumberFormatInfo is ambiguous for parsing.

What to do?
