Here's my computer specs: Pentium (R) 4 CPU 2.20 GHz, 2.19 GHz, 256 MB of RAM. Free space on C Disc: 5.10 GB, Free Space on F Disc: 4.29 GB.
I've never had a problem running CEP except when I was down to about 1 GB of space, which would cause the program to shut down a lot. Once I freed up space, it's been working just fine.
Yes, I do have back ups of my files so I can tinker with the sample rate. I will try the conversion process solo.guitar mentioned and see if that fixes it. Will let you know.
