Can't run Empire. How do I fix it?

[Mike9876]

Hi, I have Kali Linux 64-bit on VMware and Windows 10 Host. I'm following a book for Kali. My problem is with Empire. A few days ago I got the error:
splinter 0.8.0 has requirement selenium>=3.8.1, but you'll have selenium 3.5.0 which is incompatible.
So, I downloaded selenium 3.8.1 but I don't know how to install it. Can anyone explain how? Then I tried reinstalling Empire and now I get the error:
Traceback (most recent call last):
File "./empire", line 1397, in <module>
main = empire.MainMenu(args=args)
File "/opt/Empire/lib/common/empire.py", line 92, in __init__
(self.isroot, self.installPath, self.ipWhiteList, self.ipBlackList, self.obfuscate, self.obfuscateCommand) = helpers.get_config('rootuser, install_path,ip_whitelist,ip_blacklist,obfuscate,o bfuscate_command')
TypeError: 'NoneType' object is not iterable

Does anyone know how to install selenium 1.8.3 and fix Empire so I can continue reading? Please reply. Thanks

Hi, I'm back. I think I fixed it. I ran "reset.sh" and now Empire starts fine. After running a cme command from my book I no longer get the selenium error. I do get one saying:
Error authenticating to Empire's RESTful API server!
Does anyone know how I can fix that?
