Thanks just seen the post. But it claims it has been sorted, yet I have the same problem even after running a complete update. maybe the mirror my update used has not yet got the updated files yet or maybe its an incompatibility with my system. But thanks for pointing it out. I should have looked closer before posting.
But after reading the other post I found the log file. Here is a cut and paste of it.
