DO process runs, can't get lister to open

Help & Support
1

Suddenly evaluation DO won't open lister. Icon shows, process runs and stays in Task Manager list, but won't open lister.

Removed DO, reinstalled, ran istream.zip, tried in Safe Mode, nothing.

Please help.

Well the first obvious question is, did the evaluation period expire?

If that's not the situation, you might look into problems regarding your firewall or anti virus program (disable each one at a time and see if Opus launches).

How are you attempting to open a lister?
