Metabolizer for Mac Input Structure Error

I am new to ChemAxon Metabolizer. I am trying to learn Metabolizer, using the Mac version. I am running Mac OS X 10.9.4 and Java 1.6.0_65. I have tried Metabolizer 6.3.0 as well as 14.7.14. When I do File/Open, MarvinSketch opens, but when I draw a structure, nothing happens in Metabolizer. If I draw a structure with MarvinSketch and save it as a sdf file, when I try to open the structure in Metabolizer, I get an error saying that the structure is corrupt or not a valid Metabolizer structure. I have tried this on two different machines with the same result. Thank you for any help you might be able to provide.

This issue has been solved. I didn't have the window large enough to see the "Accept" button! Metabolizer is working just fine! My apologies for a false alarm.

I am glad that the problem has been solved so quickly. I think we need to check the sketcher window size on Mac, anyway. Thank you for the helpful information.
