Hello, 
 I understand you're having trouble opening your termbase in MultiTerm 2017 and 2021 due to an unsupported version error. This issue can occur if the termbase was created with a version of MultiTerm that is not compatible with the one you're currently using. 
 Here's a step-by-step guide on how to fix this issue: 
 Step 1: Create a backup of the termbase file. This is to ensure you have a copy in case anything goes wrong. 
 Step 2: Rename the termbase .sdltb file by adding the extension .mdb. The file name should now look like this: termbasename.sdltb.mdb. 
 Step 3: Open the file in Microsoft Access 2003 or a later version. 
 Step 4: Allow Microsoft Access to automatically fix any issues existing in the file. 
 Step 5: Save and close Microsoft Access. 
 Step 6: Rename the file by removing the extension .mdb. The file name should now be back to its original format: termbasename.sdltb. 
 After following these steps, your termbase should be fixed and you should be able to open it in MultiTerm Desktop and attach it to a project in Trados Studio. 
 Please note that this process requires Microsoft Access. If you don't have it, you might need to install it or find a computer that has it installed. 
 I hope this helps! If you have any other questions or need further assistance, feel free to ask. 
 Best regards,
