Oh gosh, I wish I could! I've never used Gradient Strip though, and have long been out of coding for a hobby - I've spent the last five years working in a completely unrelated field and wouldn't know where to begin now, with all the changes that would have been made to DW's backend in that time. I know S1/core 1 lj layouts are not something they intend to provide support for (I remember reading this in a newsletter, I think? It's basically to do with the redesign of lj's original raw code and the way DW has been structured; porting S1 and core 1 styles is problematic at the best of times, as that thread of mine above will show you!), but you could try poking around in the coding comms to see if someone with more up to date knowledge is around. Or the OP might still have some ideas! I'd imagine that any number of things could be causing the errors, between the updates that would have happened on both lj and dw. Sorry I can't be of more use - but I think I'd probably cause more errors than I'd fix now :(
