Missing plug-ins!

I just noticed that a couple of my old plug-ins are no longer showing up. One of them ‘Send on Bar’ was made for me by one of the kind people here and I desperately need it! I’ve no idea when it disappeared, because it’s a while since I’ve needed it.

I tried moving the plug-in, but nothing I do has it showing up, or even showing the folder it lives in. Aargh!

Heeelp!!!

I’ve just seen that it’s a 32-bit plug. Is that the problem?

(Another plug-in is causing Cantabile to crash when it finds it on a Full Scan. Specifically this one:
Spectral Compressor
Not so bothered about this one, but worth mentioning. The other one is critical to me!!)
