Siemens s7-300

I have a Siemens S7-300 that I dont have the original program for and I am using tia portal version 13 and trying to download the program. It sees it as a accessible device but when I try to upload the program I get an error. My question is should I try and later version of portal? I am down loading the trial version of version 15 now. i am a novice with Siemens and this is giving me fits. thanks in advance for any help anyone can give.

Try uploading from the PLC using STEP 7 V5.6:

If your S7-300 CPU is old enough, the firmware may need upgrading to be compatible, or it may not be compatible with TIA Portal at all. Post your CPU part number, and firmware version, if it's displayed via Online & Diagnostics under Accessible Devices in TIA Portal.
