Auto Screen Capture 2.5.1.0

Fixed issues with the SFTP client and failed screenshot uploads to an SFTP server. A null reference exception error would be thrown during a series of attempts in uploading screenshots that previously failed to upload causing the user to exit the application and start the application again (thereby voiding the failed upload process). It was also discovered that, when screenshots that had previously failed to upload, would upload successfully later (after establishing a successful connection with the SFTP server) the screenshots would be uploaded to the incorrect location. They would be uploaded based on the Folder path and the Macro path instead of simply the Macro path (as they usually do upon successful upload). Now screenshots that previously failed to upload will be uploaded based on the Macro path to keep it consistent with how successfully uploaded screenshots are handled.
