Siemens S7 lite to S7 Full

I have a couple of programs I used S7 lite to down load, now I have purchased the full blown S7 and it will not read my lite files? The file extensions on the lite files are K7P. Any help would be greatly appreciated.

Hello cornbread;
Have a look at the following articles from Siemens' support website:

How can you import the hardware configuration from STEP 7 Lite to STEP 7 and vice versa?
And
How can you transfer a STEP 7 Lite user program to STEP 7 / STEP 7 Mini?

Hope these help,
Daniel Chartier
