Powersploit Opening Session Problem

Ok, so i got the correct version of invoke-shellcode.ps1 loaded onto my computer but now when i attempt to invoke-shellcode the reverse http payload it crashes the powershell on the target computer and the handler i set up gets this message

192.168.1.190:1741 Unknown request to /INITM with UA 'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)'

I've tried to look elsewhere for a fix but nobody else has had this problem, sorry to bother you
