When login POS I was prompted a message that my license limited to 200 transaction only, after I go to Windows Start > AutoCount POS 5.0 > AutoCount POS 5.0 Database Configuration > Tools > License Control > the license status shows Stale State, how can I fix this issue?
Possible Reason :
System license file or database license data corrupted.
Computer date had been reset due to certain circumstances
1. Close the screen then go to Tools > SQL Query
2. Enter the password (if you don’t know please contact your software provider) > OK
3. Enter statement: delete from possetting > click Execute > close it.
4a. For POS user Go to C:\ProgramData\AutoCount\POS 5.0\ > delete 2 files (POSID.config & session_xxx.key)
4b. For F&B user Go to C:\ProgramData\AutoCount\FnB 5.0\ > delete 2 files (POSID.config & session_xxx.key)
5. Go back to Database Configuration > Tools > License Control > Next > (follow the steps to insert back the license)
