Finally, after doing many things and installing scriptcase manually all over again i was able to access settings page of my old installation. I quickly did a full backup. I was still getting errors when i ran scriptcase after manual installation. Anyway i was able to at least create a full backup.
I uninstalled scriptcase and other components that i have manually installed and installed it again using auto installer. But i was still getting errors. I think that because of my manually installed crap still there.
I have reformatted the new hard drive -> installed win 7 -> installed scriptcase with auto installer. Then scriptcase started without errors. I restored the backup i created earlier and it is now all good. Generated the code and all seems to be running ok.
Thanks heaps Albert for your help and pointing me in the right direction.
PS: I thought i had active support but it was expired. I did not know that support tickets expiring in two months. Previously it was valid for 1 year? Somehow i missed the fine print when i upgraded my license this year and purchased 10 tickets hoping i have support for another year in an emergency. If i knew the expiry date stuff i wouldn’t buy the tickets that time as i wasn’t in need for support. Anyway my mistake.
