Devonthink PRO or Office hangs while importing

DT Pro or Office 2.0 pb1 hangs while importing some large PDF files. I was able to import over 3k small PDF files from a previous version database without problems. But some large (20 Mb to 50 Mb) seems to hang DT at the end of the process. When I force quit and reopen the database and try a Verify & Repair, it tells me the files are orphaned but it hangs again in the process of fixing the database. I tried disabling Spotlight in the database and cleaning all caches and preferences. My previous version of DT did not have this problem with such files. Any suggestions?
