hv.vline works in patch but won't upload

[RobertoHuge]

I added the hv.vline object to my pd patch on Windows 7. I pasted the file to C/Program Files (x86)/Pd/extra It works fine in the patch, but won't upload and gives the following errors:

_main.pd in "_main.pd" @ (x:0, y:0): Don't know how to parse object "hv.vline". Is it an object supported by Heavy? Is it an abstraction? Have the search paths been correctly configured?

_main.pd in "_main.pd" @ (x:0, y:0): There was an error while connecting two objects. Have all objects been correctly instantiated? Have all inlets and outlets been declared?

[comment text] in "_main.pd" @ (x:0, y:0): Connection made to non-existent inlet at [comment {u'text': 'null object placeholder (hv.vline)'}]:0.

Any ideas how I can resolve this?
