PDF, PPT and PPS files

I am currently using WebExplorer Free and have enjoyed many of features but have encountered problems three specific file types.  PDF, PPT and PPS 

The PowerPoint files will open when browse is selected but will get an invalid filename when you try to open them.  Something similar occures when opening PDF files except that the browse will not work either.

Any suggestions, comments on how to correct this?????

Thanks
