Hello, I was wondering if someone could provide me with some help please. I hadn't used Lanchbox in a while and was still on v10.10 - I took the plunge and went to v12.6. Things seem to work fine expect when I import a new game and it tries to download images it crashes with the error: The directory name is invalid. App: LaunchBox Version: 12.6 Type: System.IO.IOException Site: System.String GetTempFileName() Source: System.Private.CoreLib at System.IO.Path.GetTempFileName() at Unbroken.RushDownloader.Download(String url, String destinationPath, Action`2 progressAction, Func`1 getCancelledFunc) at Unbroken.LaunchBox.Windows.Processes.ImageDownloader.ProcessQueue(Func`1 isCancelled, String activeImageGroup, Action`2 onIndeterminateUpdate, Action`4 onUpdateAction, Action`2 onGameImageDownloaded) at Unbroken.LaunchBox.Windows.Desktop.ImageDownloaderHelp.<>c.CountTraversalSpecification() at Unbroken.LaunchBox.Windows.Threading.<>c__DisplayClass0_0.SortCommonException(Object ) at Unbroken.LaunchBox.Windows.Threading.<>c__DisplayClass0_0.QueryDrivenSpecification() at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() I guess I left it too long in between upgrades? Do I have to start all over again? Hopefully my current setup can be saved... Thanks in advance for any help or pointers you may be able to give me.
