How to unlock a template file?

I've installed a 32-bit Metastock program in my 64-bit Windows 7. The program uses lots of templates and I imported them from a 32-bit Windows XP system. They work well but when I create a new template in Windows 7 the icon for that template has a golden lock attached to it. I can delete the template but I can't copy it, edit it, or replace another template with it.

There are several posts in this Forum but I couldn't determine if they were talking about the same problem I have and I really didn't understand the fixes recommended. Looks like Microsoft has created a clever but obscure procedure that's hard to change.

Anyway, any help you can give will be appreciated.

I installed and ran the Take Ownership program and I'm the owner of the template in question. However, it was still locked. Next I ran the program in Administrator mode and that unlocked the template. However, several customfunctions, i.e. those I wrote, used it the template disappeared and weren't available. I next ran it in Windows XP compatibility mode with the same results. The template was unlocked but the some of the custom functions weren't available. Don't know what to do about this.
