Old translator memory (.tmw) requires an administrator password that doesn't exist

My office just modernized the translator suites but didn't "properly" export the translator memory from WorkBench before jumping to Trados Studio 2021. We have the old translator memory in .tmw format, but when trying to upgrade the memory using SDL Trados Compatibility and Migration Power Pack, it asks for an administrator password that doesn't exist. We no longer have WorkBench to try the export feature. Any ideas on how to upgrade the old translator memory or remove this password?
