Error after install to login admin

[augirl]

Hi

I have a membership script that installs ok but when I click to login admin
I get this error. Tried to work it out but was unsuccessful.
Can someone help please.
Warning: fopen(/full/path/to/site/templates/admin/loginForm.html) [function.fopen]: failed to open stream: No such file or directory in /home/aussieso/public_html/class/ClassAdmin.php on line 21
No Datas

Thank you

Try asking the author of the program. Obviously a file is missing, and you need it.
