problem tryin to start R Commander

Hi, I am very new into this program. I have installed R commander using the command >install.packages("Rcmdr", dependecies=T). However, when I try to activate the commander, either via >library(Rcmdr) or via de menu, i get an error message, it says as follows:

Cargando paquete requerido: splines
Cargando paquete requerido: RcmdrMisc
Cargando paquete requerido: car
Cargando paquete requerido: carData
Cargando paquete requerido: sandwich
Cargando paquete requerido: effects
lattice theme set by effectsTheme()
See ?effectsTheme for details.
Error: package or namespace load failed for ‘Rcmdr’:
.onLoad falló en loadNamespace() para 'tcltk2', detalles:
llamada: file.exists("~/.Rtk2theme")
error: problema de conversión de nombre de archivo -- ¿nombre del archivo demasiado largo?

What can I do to solve it? I have already tried re-starting the program, adn even deleting the program and intalling it again.
