actually this plugin was of
VB 3.6.8...
aur us kay baad buhut say version release ho chukay hain...
like 3.7.x series..
aur abh 3.8.x series... yahan laga huya hay...
yeh module 2008 main lagaya tha aur tab say chal raha hay...
but yeh 3.8.x ke saath compatible nahi hay... is liye yeh error day raha hay..
so no problem..
chalay ga...
thanks for showing the error..
