Failed to correct instrumentation

[Ozaru]

I tried to correct the instrumentation shown for:
http://imslp.org/wiki/A_Collection_of_O ... Francesco)
as it implies it is a flute/violin duo but it is actually flute/cello or violin/cello.

However, when I try to edit the page and change
|Tags=dances ; hpd ; vc ; fl/vn
into
|Tags=dances ; hpd ; vc ; fl/vc ; vn/vc
it fails every time (it produces a Captcha "type the two words below" but the two words never appear - I tried in three separate browsers).

If someone else could correct this, it would be appreciated.

If you're unsure about the tagging system it's better just to mention the problem on the work's talk page, because you caused a system error with your changes. I've fixed it for you now.
