problem with getting Historical data for futures using I Brokers package

Thanks that helped but now it is giving another error.

here is the code:

t<-twsFUT(symbol="WPRO",exch="NSE",expiry="201105",currency="INR",include_expired
= '1')

       WPRO <- reqHistoricalData(tws,t ,file="Wipro.csv" ,bar="1 min",
dur="5 D") 

TWS Message: 2 -1 2104 Market data farm connection is OK:hkfarm 
waiting for TWS reply on WPRO ......failed.
Warning message:
In errorHandler(con, verbose, OK = c(165, 300, 366, 2104, 2106,  :
  Historical Market Data Service error message:HMDS query returned no data:
WIPRO11MAYFUT at NSE Trades

Is it something to do the ticker?
