Everything seems to be working ok now. Uploaded 4 videos and they run ok. Went to do a fifth and get this message?

ERROR: Failed to open /home/mmvideos/public_html/templates_c/8112db0a15de3e427fb5cf9c441149c0.params

Tried video in both .mov and .wmv formats to no avail. So not sure what this means.
Please advise.
