Database wiped after running changedbserver.bat?

Hi guys,

Huge problem here! I'll try to explain..

I was having trouble configuring mail server properties in SDP7.0, so i decided trying to restart the SDP service on my server. Closing the service went ok.
When i ran run.bat i got the message that the account i was using to connect to the database has a expired password - i then went to the SQL server and reset the password on the specific account.

Went back to the SDP server and ran changedbserver.bat in order to see if i could connect to the database - all went well and connection was established. The script gave me a popup stating that "the database 'ServiceDesk' already exists' before stating that the connection was succesful.

I then started the SDP service using Run.bat - No problem.

BUT - when going to localhost:8080 i couldnt log on using domain credentials. This is when i began to dred for what might have happened...logged on using administrator/administrator, and found that all data and configuration had disappeared.

Has anybody got any idea asto what might have happened here?
Do i need to re-initialize the database in any way to get my data back?

Unfortunantly, i didn't make a backup of the servicedesk database before doing this as im still testing..did have the time to enter 150 assets though
