VJDBC(5273) R RJDBC Fatal at Random

Have you upgraded/re-installed R or any other package  or it started NOT working suddenly? 

It started NOT working suddenly. I went ahead and re-installed R, still it isn't functioning.
In an attempt to get things up and running again I went and installed the Client for Windows. Oddly, I have to reinstall Vertica's .Net Client (vertica-client-6.1.3-0.32.exe) every startup, other wise I get a 

[RODBC] ERROR: state IM014, code 0, message [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

Incidentally when I install the driver, while SQL Management Studio (2008R2 / 2012) is closed, I get an "Exception has been thrown by the target of an invocation" Every time I attempt to start it or Visual Studio 2008 / 2010 / 2012
Once I restart my machine, the Vertica Driver is 'missing', SMS runs correctly, and the RODBC returns to giving the aforementioned error. It seems like there is a registry conflict between teh vertica-client / the jdbc driver / and windows. Would any one have any ideas on how to remedy this?

R package is: RODBC_1.3-10

I am running:
MS Sql Server 2008 R2 / 2012(x64)
Visual Studio 2008 / 2010 / 2012

The consequences . . .  my R algorithm development and my ETL efforts are disconnected and I have to restart when switching between tasks. . . 
Oh. . . Incidentally, I have been able to replicate this on another Window's 7 (x86) machine. . . same story second verse

I am getting the same error (though I have never gotten it to work). Thanks for any help:

Error in .jcall(drv@jdrv, "Ljava/sql/Connection;", "connect", as.character(url)[1],  :   java.sql.SQLNonTransientConnectionException: [Vertica][VJDBC](5273) FATAL: Unsupported frontend protocol 3.4: server supports 3.0 to 3.3

Some additional information, I recently ran into this error.

I have two clusters, first one has Vertica 6.1 installed (and a running Vertica DB). Second one has Vertica 7.1 installed (and a second independent Vertica DB).

By using a putty console i can connect to each cluster, then use vsql to connect to their correspondent Vertica DB. However, if I connect to cluster #2 and try to connect to the Vertica DB of cluster #1 it returns the error

I am convinced this has to do with the driver version that vsql is using in cluster # 2.

Hope this helps you
