Check one thing on your invoice. there may be an extra space before the last set of digits. Watch for that.

If this is not it, send a note to support at softraid. I cannot post your license online.

Based on what you wrote, it would appear that some kind of flag is improperly set, despite having a valid serial number. Please remember that the Lite version had been working, before it suddenly started saying "invalid serial number."

Must have been a typo, it was entered correctly in your support file. I don't want to post it for obvious reasons.

It is easy to miss something, but I saw your middle set was QAQ67. Maybe you entered one or both of the Q's as 0? It is OK at present, SoftRAID sees a valid license, so running SoftRAID retail should fix you up.

You should run the SoftRAID app, not lite, your license is for full SoftRAID.

Attach it to the forum. When you create it, all that happens is it is saved locally.

Serial numbers cannot change. We dealt with this in direct support, but your serial was never for SoftRAID, it was for XT, which was corrected.

But it did not "change". I have an idea what happened, but your log did not have enough history to be sure.
