Hi, for some reason Zotero has stopped opening.

When I open the application I get the following error message:

"The proedure entry point ??0Decimal@Webcore@@QAE@ABV01@@Z could not be located in the dynamic link library C:\Program Files (x86)\Zotero Standalone\xulrunner\xul.dll"

I then can only press OK, which takes me to another error box saying:

"Couldn't load XPCOM."


Anyone able to help? I am not particularly great on computers!
