Actually it was version 6 of LW that introduced the new format. Poser only supports the earlier 5.x style .lwo. If you have LW 6.x or higher, you can save out as 5.0 .lwo, but note the 5.0 .lwo support neither groups nor UV maps. If you have LW 7.5, a better option is export as wavefront object .obj, which supports both groups and uv maps and works pretty well for Poser. The error message is confusing, Poser doesn't have a plugin that supports 6.x style .lwo so it just kind of a generic error. Poser currently doesn't have a plugin capable of importing 6.x LW objects.
