Monitoring Citrix Licenses

I was trying to monitor our citrix license use with OpManager. This would be a great thing for us to consider buying this product.
As most I've tried loading the delivered mib with no success.
The MIB here > http://forums.manageengine.com/forumHome.do?forumGroupId=49000000002007&forumTopicId=49000002631833
is no longer available. Hopefully someone still has this fixed mib laying around?

Then I have a second question. We are running a server farm and a licensing server.
I don't know how to get data out of the licensing server. But I can get the activesessions from the citrix servers.
Is there a way for me to count all the server sessions together and put them in a variable somewhere?
Perhaps to 1, or all (easier to monitor) of the servers. Because the total of all sessions on all servers is what counts.

Any ideas?
Thanks in advance!
