Paste Problem!

Good morning Smile

I've ran into an issue with my paste function in CorelDraw X5. When I click copy or press ctrl+c, it appears to copy the data to clipboard but nothing happens if I click paste or press ctrl+v.
The duplicate (ctrl+d) function works just fine and I can copy stuff into Corel from other programmes like Word. the problem I'm facing only seems to affect copying and pasting objects. It won't work pasting into the same document or a new document either.

Reinstalling Corel doesn't work nor does reinstalling Windows entirely.

Can anyone help with this please? Thanks!
