thanks for your quick reply. unforunately, it is the offline version that i have installed. the recommended version never downloaded at all, so i went for the offline. any other suggestions? can i get version 4.10.9 back? i tried a system restore on my PC and the 4.10.9 icon reappeared on my desktop, but when i tried to open it, it was version 4.12.4 that opened and failed. i appreciate your help.
