Looks like your issue is with SS feed nor RSSMagician. You posted in wrong place or i am missing something?!
I have the same problem with wrong RSS format and it says XML error: Invalid character at line 157, column 27. Feed validator reports about bunch of errors like:
line 155, column 81: 'utf8' codec can't decode byte 0xa1 in position 13863: unexpected code byte (maybe a high-bit character?)
line 16, column 4: description should not contain relative URL references: /store/click.php?l=aHR0cDovL3d3dy5hbWF6b24uY29tL2dwL3JlZGlyZWN0Lmh0bWwlM0ZBU0lOPUIwMDBWOUNHRVMlMjZ0YWc9dHJ1Y2twcm9kdWN0cy0yMCUyNmxjb2RlPXhtMiUyNmNJRD0yMDI1JTI2Y2NtSUQ9MTY1OTUzJTI2bG9jYXRpb249L28vQVNJTi9CMDAwVjlDR0VTJTI1M0ZTdWJzY3JpcHRpb25JZD0xUlhQMEhLN1JNWlBIMEQ3VjVSMg%3D%3D (147 occurrences)
line 155, column 80: description contains bad characters (2 occurrences)
line 1626, column 0: Missing atom:link with rel="self"
Any ideas how this can be resolved?
thanks in advance for the quick response
