Creo Parametric Design_EssH Chinese can't be reconginizable

I am using Creo Parametric Release 5.0 and Datecode5.0.6.0 I currently need to work from home, so I am using the Home Edition license of PROE_DesignEssH in my home office environment. I need to open *.drw files created by my colleagues using PROE_DesignEss (155) (which includes the Creo Language Option License—CHINESE (formerly Pro/ENGINEER)), but the Chinese characters in these files appear as squares (unreadable). How can I resolve this issue, since I need to continue working from home? Thank you. Here are the errors that I faced The characters are displayed as squares (unrecognizable)
