Thanks DUIT!
Yes it is.
MAke sure your version 7 client is set to EXPERT and then you click on the configure tab and then to the far right there is the expert tab.
On the bottom of the left hand side is where you click ADD and then type in: CLIENT-TYPE on the top and: BETA on the bottom. Click save.
After this you go find your FAH_15 core in windows explorer and remove the one that is in there and replace it with the one ArVee and Mark supplied that is the 2.22 version.
Close it up and you are ready to go.
You should try it!
