Limitations in excel bom import

Hi All, request you to please let me know  the limitations on the windchill trial version downloaded from the website link below :

i feel that the trial version is taking only 10 rows of data from the imported BOM xl sheet hence i am not able to import all the components from the excel sheet bom.

thanks in advance
