I sent them a note about your problem; see if I have more luck.

Epc won't work with Java 7.
You must uninstall it.
Then load Java 6

EPC works fine with Java 7. I've been running it without problems for a while now.

I would check and make sure the time and date are correct on the machine. Incorrect time and date will cause certificate validation failures. I know this is true in browsers. It might be true for Java applications as well.

I have the same problem with mine. My 2 computers at home also have certificate issues but the one at the office works fine. All run the latest Opear browser and java7. At home I run Win7 and WinXP sp2 and at work win xp sp3.
One big difference is that I run Avira antivirus at home and we use Mcafee at the office. I have looked for system reguirements needed to run EPC but can't find anything. The forum is in german so that doesn't help either.

Attached is the error I receive.

Thanks for your assistance. Have yet to hear back from them. I was running avast & have recently changed but get the same error. I'm sure the issue is with Java.

So far no response beyond the automated one they send upon receipt of the email. Are you using the same computers that you previously were able to launch it on?
