I have reset the lightroom preferences it has worked which is really good, there is always a BUT. I think what it has done is reset the preferences to default all goods everything looks like its back in place, here comes the but, looks like all my catalogs are gone for what ever reason, so i think i might be back to square one. Not sure what the next set is.
To everyone that commented i may not know any of you personally but, i really apreciate the comments and help each of you have given thanks so much.
I found this link also last night while having a chat to Goose over the problem. I haven't given it a try yet but I think its the next option I will try when I get in tonight. I will let you know how I get on.
