First, make sure that you are using the latest version of the product. Upgrades are available at no extra cost for those with a subscription. You can use the following link for information on accessing the latest version: Downloading OpenFlows | Hydraulics and Hydrology software.

If that doesn't help, try the following steps: 

First, close the model but leave the software open. Go to File > Database Utilities > Compact Database. Select the database file associated with the model and, when prompted, choose the option to purge the model to save space.

If that doesn't help, close the model (you can leave the software open). In File Explorer, browse to where the model files are saved and create a new folder. Copy just the .stsw and .stsw.sqlite files into the new folder, then open the model files from the new folder location.

If that doesn't help, you can try imporingt the database file into a new drawing by going to File > Import > (product name) database. (or select "database files" from the "files of type" dropdown in the file open dialog)
