Troubles with zotero

I have very problems with zotero. When I get to start my library it appear the followig warning: ''Zotero user data DB version is newer than SQL file''. How do I do?
  • You most likely installed the 1.5 Sync Preview and then tried to revert back to Zotero 1.0.7, which won't work.
  • Hi Dan.
    It was exactly that I did...and then, what i will do now? could I install Zotero Sync again?
  • Yes, you should be able to reinstall the sync preview and access your collection again.
