2.1b2 -- Error starting zotero in 4.0b8pre and 4.0b6

Upgraded zotero to 2.1b2 and it stopped working with 4.0b8pre and 4.0b6. I get an "error starting zotero" error and a yellow triangle on the zotero icon in the status bar.

The upgrade works fine with 3.6.12 though!

The debug logs are:

[Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FO
UND) [nsIFileInputStream.init]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)
" location: "JS frame :: chrome://zotero/content/xpcom/schema.js :: _getSchemaS
QLVersion :: line 1004" data: no]
