Hi guys :)
	I`m new to ocsinventory and i have a problem now:
	first of all, I`ve successfully set up the OCS Server and deployed over 250 Agents, all these agents are working fine.
	but recently I reinstalled the agent on my PC and deleted the host on the server, then here comes the problem.
	I kept receiving errors in Windows log, as I posted here:
	Service encounter error <Failed to load/parse last inventory state>.
	I`m not sure if this is the reason but I do cannot see the same mistake on other computers that is working fine.
	and also, I`ll POST part of ocsinventory.log  :
:
	INVENTORY => XML Update 5 Printer(s)
	INVENTORY => XML Update 457 Software
	INVENTORY => XML Update 0 Registry Value(s)
	INVENTORY => XML Update Administrative Information(s)
	INVENTORY => XML Update common Device properties
	COM SERVER => Initializing cURL library for sendRequest
	COM SERVER => Using cURL without server authentication
	COM SERVER => Disabling cURL proxy support
	COM SERVER => Enabling cURL SSL server validation support using CA Bundle <C:\ProgramData\OCS Inventory NG\Agent\cacert.pem>
	COM SERVER => Sending HTTP Post request to URL <http://10.243.16.76:8080/ocsinventory>
	COM SERVER => HTTP Post response received <HTTP Status Code #500>
	COM SERVER => Cleaning cURL library
	ERROR *** AGENT => Failed to send Inventory <HTTP Status Code #500>
	AGENT =>  Communication Server ask for Package Download
	DOWNLOAD => Package history file successfully cleaned for duplicate IDs
	DOWNLOAD => Download disabled by server
	AGENT => Unloading communication provider
	AGENT => Unloading plug-in(s)
	AGENT => Execution duration: 00:00:15.
	
	
		as you can see I have a HTTP Status Code #500 error here. So I`ll just Also POST Apache Error.log here :)

				I can see thousands of the same error above.
			
				But since all other agents are working fine(Saying working fine, I mean I can even see these computers still contacting server just now.),I believe there is something wrong with my computer istead of the server.
			
				ahmmm...I almost forget, here is my ocsinventory.ini :)
