Error: nrComm in Dterminal with Delphi 5 : nrSemaphore.Style3D doesn't exist

[sciensoria]

Hi,
I intend to buy nrComm for use with new USB-RS232 cables which uses high COM numbers (>10, for example COM35).
However, an error persists: when I try to execute DTerminal, there was all the time an error: nrSemaphore1.Style3D doesn't exist. The error occurs during execution under Delphi 5 environment or with the Dterminal.exe file.
I downloaded 2 versions (5 MB and 20MB) of nrComm VCL but both have this error.
Could you help me to fix this error ? I am in a hurry, I have to do something for the next week.
Thank you in advance.
