Well, finally got it running again. I have two T440s machines, one worked with Easyslides, the other didn’t. So I removed the hard drive from the non-working machine, attached it with a USB/IDE adapter to the working machine and cloned the working machine’s hard drive. This gave me a (possibly uncorrupted) operating system and, of course, Easyslides was on the disk – but it still didn’t work! Deleted Easyslides from hard disc clone and installed Easyslides 5.2 Beta and, BINGO, a working Easyslides. What was the problem, blowed if I know, but 5.2 seems to have sorted it. Would it have done it without making a clone of the other disk? Who knows!
