Need help cacti not working ;it 's an urgency please

[rtsiresy]

hello,
so I just installed cacti 1.1.38 with rrdtool 1.2.15
I created a windows device , then added data queries and graphs template for the device;
I tested if polling cycle is working by running poller on command prompt and it is okay; rra files were created;so I continued with the task scheduler ... but the graph is not showing; and there's lot of errors that I cannot understand in the log file ...

The thing is it's a scolar project and it'll be checked for this week , I took a while trying to figure this out but hopeless ... so I am really begging for help please ...
Thank you
