ClarisWorks: Error -50 Opening Files While Using Empower or FileGuard

This information was provided by Claris Corporation on 16 March 1998, and incorporated into Apple Computer's Tech Info Library.
This issue is corrected in ClarisWorks 1.0v3.

A conflict with Empower II 4.0 and FileGuard 2.7 and above prevents ClarisWorks 1.0v2 and earlier from opening saved files.

When opening a document, you may receive an error -50, "Error in user parameter list".
