Cant open DTTG since iOS5 update

UPDATE: Downloaded the new update and this is fixed! Thank you.

I can no longer open DTTG on my iPad 1 after upgrading to iOS5. App opens, then crashes, before fully launching. To clarify, DTTG does work when there’s no data in it (works fine if I delete and reinstall) but once I synch my database (about 7k entries, 4g) it no longer opens.

Any suggestions?
