Error after changes in workflow file (.wft)

Question

Hello Friends,
I have got one customization request in workflow notifications and that required changes in standard packages.
I have made custom copies of those with required changes and then opened workflow file in wordpad and replaced the standard package with the custom copy( I guess this is the method to do it , if there is any other pls let me know) in wft file.
But i am getting errors which indicate that workflow is not able to call the custom components. The error is saying that package is invalid but when i checked from backend , the package status is valid.
Is this an issue with access level in workflow?
Please help.
Regards,
Amit
