When I run the R Script given below, I get the Error Message as shown below the R Script. This R Script used to work on my laptop but, it stopped working after re-imaged my laptop. Blank capturefile1cf05291409.ps file however, gets created in working directory when I run the script. I don't understand what file/folder I am missing on my laptop. Requesting help to fix this issue.

The R Script:
library(motifStack)
pcm<-matrix(runif(40,0,100),nrow=4,ncol=10)
pfm<-pcm2pfm(pcm)
rownames(pfm)<-c("A","C","G","T")
motif <- new("pfm", mat=pfm, name="bin_SOLEXA")
plotMotifLogoA(motif)

The Error Message:

Error in PostScriptTrace(paste(psfilename, ".ps", sep = ""), paste(psfilename,  :
