Error message when opening my translation memory

Question

Hello,

I get an error message when opening my translation memory in Trados Studio. I have attached the error log. Unfortunately, the plug-in for repairing the TM did not work.

I use Trados Studio 2024.

Thank you in advance.

Best regards, Heiko Stegmeier

 Question improvement suggestion: Please provide the exact error message you receive when attempting to open the translation memory, as well as any specific steps you have already taken to troubleshoot the issue. 
 In the meantime, based on the information you have provided, here is a suggested answer to your question: 
 Hello Heiko, 
 It seems you're encountering an issue with opening your translation memory in Trados Studio 2024. Based on the error message you provided, it appears that there may be a problem with the translation memory file itself. Here are some steps you can take to troubleshoot and potentially resolve the issue: 
 **Step 1:** Close Trados Studio completely. 
 **Step 2:** Navigate to the following directory on your computer: 
 - For Trados Studio 2024: `C:\Users\%Username%\AppData\Local\SDL\SDL Trados Studio\Studio17` 
 - For Trados Studio 2021: `C:\Users\%Username%\AppData\Local\SDL\SDL Trados Studio\Studio16` 
 **Step 3:** Look for the file named `Translation Memory Repository.xml` and rename it to `Translation Memory Repository_old.xml`. This file lists all translation memories and renaming it can help reset the memory list. 
 **Step 4:** Restart Trados Studio and try to open your translation memory again. 
 **Step 5:** If the issue persists, consider using the SDLTM Repair tool, which you can download from the RWS AppStore. This tool may help repair any corruption in the translation memory. 
 **Step 6:** If the repair tool does not resolve the issue, it may indicate that the translation memory is damaged at a database level. In this case, you might need to restore from a backup if available. 
 **Step 7:** As a last resort, if you have all the necessary files for the translation memory (including *.tmw, *.iix, *.mdf, *.mtf, and *.mwf), you can try to recreate the translation memory or seek assistance for conversion with an older version of Studio. 
 I hope these steps help you resolve the issue with your translation memory. If you have any further questions or if the problem persists, please feel free to reach out again. 
 I hope this answer addressed your question. If not, please reject the answer, add the question improvement suggestion information, and click the RWS Community AI checkbox on the right to try again.
