Hi,
First, thank you for the guide! Unfortunately I encountered issue same as this one when starting ZoneServerUD_x64.exe. Below is the error log I received
```
05-05-2024 16:22:45 22344 CAdoConnection::Open('Provider=SQLOLEDB;Source=BILLING;UID=sa;PWD=myPassword;;Initial Catalog=BILLING;') - Unspecified error - Invalid connection string attribute
05-05-2024 16:22:45 22344 CAdoConnection::Open('') - Unspecified error - [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
05-05-2024 16:22:45 22344 Warning! Failed to open connection with errors db!
05-05-2024 16:22:45 22344 ERRDB write failed: Warning! Failed to open database connection!
```
Any idea how to proceed with this?
