Questions are always welcomed, however I need cooperation in order to help you.
i really don't understand why it was difficult to help me
I'll try to explain though it is not too important.
Post #1: You posted an error and you were sure that the problem was in the new version. You quickly returned to the previous version.
Post #5: I said that it doesn't look related to the new version. BTW, I wasn't 100% sure of anything.
Post #6: You said that a restart didn't help and again returned to the previous version.
Post #8: I repeated that it doesn't look related to the new version and that it might be the anti virus.
Post #10: You haven't tried to disable the anti virus and again thought the problem is in the new version and went back to the previous version.
What do you think that I can do at this point? Repeat my same answer for the third time? Remove v8.30 from the website and revert to v8.10?
