Appcrash

[mikeg]

I've been using UR Pro 4.1c on Win 7 32-bit PC (with Office 2010 version of riched20.dll) for weeks with no problems. Now suddenly I can't even get UR to open without getting the APPCRASH below. I've uninstalled/reinstalled and tried removing riched20.dll, but nothing works so far. There were no changes to the PC that I'm aware of at the time this started happening. Any ideas?
