questions:

Are there any LOB columns (text, image, varchar(max), etc) in the tables where you truncate (delete?) the data?
do you see and how do you check that free space exists in the database?
provide the output of the following:
```
 select @@version?
```

The solution is simple. Don't shrink. There is no point in shrinking if you are going to fill up the space again. Also, shrinking the data files introduces a ton of fragmentation.

You can also read SQL Server MVP Tibor Karaszi's article on the topic:
