I received your email with the screen shot. This error appears to be happening during the Sync process. This error is stating the file is too large to complete a backup of the data into the CNH Data Vault folder within your computer. The only way to get past this error is to open the Advance Setup button and check the box to Skip Repository Synchronization. Click OK. You will get a warning message that no backup of the data will happen and click Yes or OK that you understand. The next message states that you need to browse again to the (filename).CN1. Click OK. Then click the Browse button again. Re-select the same (filename).CN1 and click Select Folder. After making the desired selections on boxes at bottom click OK. Now this error will cease, and go right into reading the data files.
