eacc :: can not ... stdclass as array on eacc.php 87

windows+apache2.2.14+php5.2.10
two situations will cause this error:

1.clear eacc's temp cache files and restart apache , your get this error while open a node page
well , this could be fixed by reinstall "cacherouter" and clear drupal's cache
and i figure out that , this error come out when using "node_load(nid)"
you can recur this error by "1.clear eacc cache folder files 2.restart apache 3.open a node"

2.i don't know how , it just come out and i could't fix it by just reinstall , and i don't change any code since it runs all right last time
still,this error come out when using "node_load(nid,NULL,TRUE)" or node_load(nid)

now ,i have to shut this module down , and wait for your advices.
i try to change code on line 87 , but since i don't know how this module work , it failed
really , this module help me to low down nearlly half of my database querys, thx a lot .
