Dynamsoft TWAIN Products

I am deploying my project on my webserver and used trial Web Twain, Now everything is working fine if i connect scanner to webserver but when i try to connect the scanner to a client machine and open the server application and when my scan page is loaded in browser i get the following error:
"YOUR DYNAMIC WEB TWAIN SERIAL NUMBER IS INVALID"

Based on the previous replies in the post for similar problems I did sent an email to twainsupport@dynamsoft.com with my webpage,lpk and cab file. Appreciate an early reply

We've checked your files, and they are correct. It is likely the system date/time on your client machine exceeds the expiration date of the trial version. Please note the trial period of Dynamic Web TWAIN is 30 days.

Would you please check if this is the case? If yes, please set the system date/time on the client machine to the present date/time.

If it does not solve your problem, please let us know.

Thanks.

Yes the system date and time is different in the clients machine. Thanks for your help
