[R] x12 doesn't work any longer

Context: Mac OS X 10.7 - R 3.0.2 GUI 1.62 Snow Leopard build (6558)

I had been using x12 for some time with no problem at all. every month I update the time series ricpesata (see below) and run the simple procedure below. Now adding the data of the last month, Sep.2013, 
x12 is complaining:

> library(x12)
> x<-x12(round(ricpesata,2), x12path="/Applications/x12arima/x12a", automdl=TRUE, decimals=2,  transform="log", outlier="all", forecast_years=2)
Error in .local(object, x12Parameter, x12BaseInfo, ...) : 
  unused arguments (x12path = "/Applications/x12arima/x12a", automdl = TRUE, decimals = 2, transform = "log", outlier = "all", forecast_years = 2)

where
> str(round(ricpesata,2))
 Time-Series [1:285] from 1990 to 2014: 20924 20559 19952 19366 19145 ...
>  

is the following timeseries:

          Jan      Feb      Mar      Apr      May      Jun      Jul      Aug      Sep      Oct      Nov      Dec
1990 20924.30 20559.41 19952.28 19365.96 19145.28 19536.69 19791.74 15796.91 19690.72 19779.16 20444.38 20529.32
1991 21155.47 21613.96 20168.89 19584.45 19527.75 19765.04 20314.15 16116.04 20232.00 20391.31 21200.69 21093.83
1992 21570.88 21877.04 21129.40 .........

What does that error mean and what should I do?

Thanks in advance
