Upgrade 6.0.1r44 for Epson 1680ExpressionPro won't accept SN

[prachun]

This weekend my computer crashed and I had to revert to a previous system restore point. I then upgraded to SilverFast Ai v6.0.1r44 for my Epson 1680 -- file "SFE-6.0.1r44(Expr1680).exe". The upgrade keeps rejecting my serial number. Normally of course, any incremental upgrade doesn't ask to re-enter the serial number, but I assume this happened because of the reversion to a past restore point.

It doesn't help that Lasersoft has created serial numbers with numerous O's and/or zeros. How the hell do I tell what's an O (letter), or the number 0 (zero)? Come on Lasersoft, we pay more than decent money for this product; why irritate your customers with these silly ambiguous serial numbers?

Now here's something interesting:
With the new r44 Epson 1680 installation, the main preview window states "Silverfast Epson CC-600PX" -- I would think this should state "Epson 1680 Epression". Has there been a mixup with "r44"? I then tried to re-install an older version "r36B", but "r44" stays put.

By the way, I had to go through the same scenario with my Nikon 8000ED Silverfast Ai install -- it worked fine and accepted my serial number! As expected, the main preview window here states "Silverfast FS-Nikon LS-8000" as it should.

Dear Prachun.

There ar no 'O' (letter) in the serial number. The serial number can consist of numbers 0..9 and letters A..F. Actually SilverFast hould convert the letter 'O' to the number '0' itself.

Are you sure, you have entered the serial number correct?

If the problem stays, please contact the support at: http://www.silverfast.com/problemreport/en.html.
