Unable to connect to cube

[mauricioromero86]

I have access to an OLAP cube which I have successfully acceded using Excel

Now, I'm trying to use X4R but R always crashes at the end of this code

library(X4R) handle <-xmlaConnect("cubos.sispro.gov.co", uid="sispro.local/mromero", pwd="mr0m3r0")

This is on R 3.1.2 (Both 32 and 64 bit version)

Any ideas on what the issue might be?
