Could not load template

Hi,
I have file called register-seller.tpl in /catalog/view/theme/default/template/account/register-seller.tpl .when i tried to register as a seller getting this error.
Notice: Error: Could not load template D:/xampp/htdocs/bluedress/catalog/view/theme/default/template/multimerch/module/accounttpl.tpl! in D:\xampp\htdocs\bluedress\vqmod\vqcache\vq2-system_storage_modification_system_library_template_basic.php on line 26

Please help me to fix this issue.

It's a Custom Extension you use, you should therefore always contact the Mod-Creator first.
But accounttpl.tpl does not exist, it should be called account.tpl
