I guess they have changed their query structure.
I use a tiny program to check whois IPs and lately I get the following from Arin :

#
# Query terms are ambiguous. The query is assumed to be:
# "n 207.46.204.190"
#
# Use "?" to get help.
#

#
# The following results may also be obtained via:
# http: //whois.arin.net/rest/nets;q=207.46.204.190?showDetails=true&showARIN=false
#

then it adds all the usual information.
I'm sure you recognize the IP. ;o)
