I used HEM for several months without problems. I could still use the import screen and run table manager but whenever I clicked on Cash Games or the other tabs, HEM would freeze and I would have to close it by pressing C+A+D.
I backed up my database and uninstalled both postgres and HEM. I did so through control panel/add remove programs. I also tried to delete the registry so that I could rid my computer completely of all traces of both programs in hopes of a clean start, although I don't think I managed to do so as I was not asked to reenter a HEM serial code upon re installation.
After reinstalling HEM and postgres and creating a new, empty database, I am still only able to access the import screen. I can import hands and run table manager but cannot click any other tables without HEM freezing.
Anti-Viruses are not an issue.
