This is a limitation of our demo version. To permanently remove the SAMPLE mark and be able to convert more than 2 files at once, you will need to get a license key from our web store.

In some cases, a user will activate the license and inadvertently try to convert a file that has the SAMPLE mark on it from previous runs. Make sure you use the original files, ones without the SAMPLE mark after you have activated the license key.

Installation Errors

A common error you may encounter is a Java-related error and this happens when you are trying to download and install the program while you have the program already open on your desktop (this affects Windows only Users).

The simple fix for this is to either: 1) restart the computer, or 2) quit the program by opening Task Manager, select the program and "End Process", OR do the following:

  • Open the Control Panel
  • Click on System and Securities, then select System
  • In the left tab, click Advanced Systems Properties
  • Select Environment Variables
  • In the System Variables box below, click New
  • Use New Variable Name: _JAVA_OPTIONS and New Variable Value: -Xmx512M, then click OK

Errors During a Conversion

If you are getting error codes when converting files, try using a lower resolution setting and reduce the number of files you are trying to convert. This could be a memory issue. In addition, if you are using an older version of the program, click here to download the latest version.

Windows Users: Open the PDF file with Adobe Reader XI (here's a link to the free download of Adobe Reader XI). Simply double click the problematic file and now it will open in Adobe Reader X. Then save the file with a new name (File>Save as>PDF), choose a new name and location. Try re-merging the newly saved file. NOTE: This is not the same as right clicking on the file and renaming it!.
