Rbloomberg problem

Hi,

I am new R user and have been trying to properly configure an R working
environment.  I  have it up and ruining except for the Rbloomberg.

I tried running the examples in the documentation. And encountered  into
several issues:  First, R2.5.1 was crashing and I could never understand
why. I installed the latest release R 2.7.0 and was eventually able to
run only tow of the examples from  blpGetData(RBloomberg)

The intraday "Intraday bars" and the "Tick-by-tick" examples do not run.
I am wondering if (1) made a mistake in the set up? Or (2) there is a
problem here with R 2.7.0 too.

Currently using
Package:       RBloomberg
Version:       0.1-10
Date:          2006-05-04
Built:         R 2.5.1; ; 2007-07-22 18:19:52; windows

Usinga lso 'RDCOMClient' version 0.92-0

Any recommendatiosn?  

blpGetData(RBloomberg) examples.

library(RBloomberg)

.bbfields <- blpReadFields("C:/Program Files/blp/API")

## Not run:
conn <- blpConnect()

## Snapshot
eda <- blpGetData(conn, c("ED5 Comdty","ED6 Comdty","ED7 Comdty",
"ED8 Comdty"), "BID")
eda

## Historical (last 30 days)
edb <- blpGetData(conn, "ED1 Comdty", "PX_LAST",
start=as.chron(Sys.time() - 86400 * 30))
edb

## Intraday bars (last hour in 2 min bars)
edc <- blpGetData(conn, "ED1 Comdty", c("BID","ASK"),
start=as.chron(Sys.time() - 3600), barfields="OPEN", barsize=2)
edc

## Tick-by-tick (3 minutes starting an hour ago)
edd <- blpGetData(conn, "ED1 Comdty", c("BID"),
start=as.chron(Sys.time() - 3600),
end=as.chron(Sys.time() - 3420), barsize=0)
edd

blpDisconnect(conn)
## End(Not run)
 

Output
