Older Tiddly won't open

[Salim Farhat]

Hello,

I got Tiddly a few years ago and I still have an older one. I'm not sure which version it is, but it is pre-2014. I added a bit of information onto it and I neglected to transfer the stuff onto the new version... and now my older one just won't open. I opened it today, made some changes, and copy-pasted the new saved wiki over my old one like I normally do... and it's not opening at all. I get a blank page and nothing else.

What can I do? I have quite a bit of information there that I want to save. :(
