License Renewal

License Renewal

Hi there,
 
Until recently we've been licensed for 10 technicians in ServiceDesk. We had this license because we had 6 technicians but one of those technicians are no longer with us, so it was my understanding that we could use the free license for up to 5 technicians.
 
Our license was due for renewal but I was advised by our vendor that we didn't need to do anything further as we only have the 5 technicians.
 
Unfortunately as of today we can no longer login as any of our technicians, or the admin account. Message encountered is "NTLM Failed Redirecting To Login Page..."
 
Perhaps it's just a coincidence we can no longer login, but can someone please let me know what we need to do to get up and running again, and if our vendor was incorrect in there below statement. 
 
" you do not need to renew the Manage Engine Service Desk software support.
 
As you have less than 5 technicians and do not need support you can just continue to use the product. "
 
Regards,
Ash.
