Xpose31 fails to be redirected to the working directory

I have been using Xpose 4 release 5.1 in R with excellent results. However, at least with my downloaded version, the bootstrap of the gam has an ' * ' infront of it indicating that this function is not yet available. Because of this I have been attempting to use the bootstrap of the gam funciton in Xpose3.1 running in Splus 6.0 (Windows Xp Professional spk 2). Xpose31 has failed to recognize the presence of the standard Xpose31 table names; SDTAB001, SDTAB01, SDTAB1, COTAB001, COTAB01, COTAB1 etc. I have created a new chapter in the subdirectory where the needed tables are located and attached that chapter accordingly. Running a search() in the Splus6 command window confirms that the working directory has been attached and is in the first location. Any ideas as to why Xpose31 is not able to recognize these tables?
