Sorry, just put that in wrong forum - isn't really a level solution, but Help please!

I've got to purple shard level, got 2 mottled keys but just discovered the items bag is full. Accidently saved over latest game so can't easily get out. Is there an easy way out - shards don't work in the void - or do I have to bite the bullet and work my way up again

I have been playing Wonderland for ages and eagerly awaited the Platinum update. I followed the instructions using Winzip to extract files and overwrote the files as reuested. However this does not seem to have worked and Return to Wonderland is still the Deluxe edition. Help please!
