lib unspecified & Error in loadNamespace

I had everything working with R and RStudio, but then I moved the folders when cleaning up my computer directories & files. Now I’m getting the error message below.

Should R and RStudio be installed under Program Files or Program Files (x86)? Should I have two libPaths?

install.packages("C:/Users/kevin/Downloads/fpp_0.5.zip", repos = NULL)
## Warning in install.packages :
##  package ‘C:/Users/kevin/Downloads/fpp_0.5.zip’
## is not available (for R version 3.0.0)
## Installing package into ‘C:/Users/kevin/Documents/R/win-library/3.0’
## (as ‘lib’ is unspecified)
## package ‘fpp’ successfully unpacked and MD5 sums checked
library("fpp", lib.loc="C:/Users/kevin/Documents/R/win-library/3.0")
Loading required package: forecast
## Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
##   there is no package called ‘colorspace’
## Error: package ‘forecast’ could not be loaded
