Ver u

hi all, this is my first post and hope someone can help. downloaded the new version U and now when i double click a exe file or indeed any file i get the message " Windows cannot access the specified device,path,or file you may not have the appropriate permissions to access the item " if i use windows explorer everything works normally as Opus did before downloading the new version
thanks for any help in advance

Not sure why that would start happening. I would try running SysInternal's FileMon to see if you can work out which file/path cannot be accessed and is causing the error.
