Hi,
If I understand you correctly, you have the database files from before but didn't back them up. If that is the case, you can take the following steps.
1. Create a new database in SQL Server with exactly the same database name as before. You could use the Primavera utility to do this and it will look after login names for you.
2. Stop your SQL Server databases through System Services
3. Cut the files that were created for the database and copy them to somewhere out of the way - just in case. On my machine they are called pmdb$primavera_DAT.mdf and pmdb$primavera_LOG.ldf. My database is called pmdb$primavera.
4. Copy only the *_DAT.mdf file from your previous installation to where you just cut the new file from.
5. Use Services to start SQL Server up.
Take a look at the answer I gave in this post

Alternatively get someone who knows SQL Server to do it for you.
