Rbbg

This is what I get when I do traceback():

con.BBG <-  blpConnect()

R version 2.15.2 (2012-10-26) 
rJava Version 0.9-3 
Rbbg Version 0.4-155 
Java environment initialized successfully.
Looking for most recent blpapi3.jar file...
Adding C:\blp\API\APIv3\JavaAPI\v3.5.1.1\lib\blpapi3.jar to Java classpath
Error in .jnew("org/findata/blpwrapper/Connection", java.log.level) : 
  org.findata.blpwrapper.WrapperException: Session not started because:
CONNECTION_FAILURE

traceback()

7: stop(list(message = "org.findata.blpwrapper.WrapperException: Session
not started because: CONNECTION_FAILURE", 
       call = .jnew("org/findata/blpwrapper/Connection", java.log.level), 
       jobj = 
<S4 object of class "jobjRef">
))
6: .External(RcreateObject, class, ..., silent = silent)
5: .jnew("org/findata/blpwrapper/Connection", java.log.level)
4: blpConnect.Java("warning", NULL, TRUE, NULL, TRUE, FALSE)
3: eval(expr, envir, enclos)
2: eval(fn.call)
1: blpConnect()

Thanks
