Error in get(referencePkg): object 'FlowSorted.Blood.EPIC' not found

This is the code I have I tried converting it to 450 and it didn't work so I tried not converting and it still did not work. As EPIC seems to be quite standard now I am unsure of why this is not working? The FlowSorted.Blood.EPIC package has been installed and re-installed several times.

Code:

library("FlowSorted.Blood.EPIC")

estimateCellCounts(RGset, 
                   compositeCellType = "Blood",
                   processMethod = "auto", 
                   probeSelect = "auto",
                   cellTypes = c("Bcell", 
                                 "CD4T", 
                                 "CD8T", 
                                 "Eos", 
                                 "Gran", 
                                 "Mono", 
                                 "Neu", 
                                 "NK"
                                ),
                   referencePlatform = "IlluminaHumanMethylationEPIC",
                   returnAll = TRUE,
                   meanPlot = TRUE,
                   verbose = TRUE)

Error:

I also tried everything mentioned in this person's StackExchange post. What do I do to navigate around this?
