I have been hunting for information on Tigal as well. Sorry to hear they have gone
I wanted to buy another Zeroplus Logic Cube from them but got the same error messages and no sign of them being active on the NET recently.
They had an excellent price on their Zeroplus 16032 logic analyser (£89+p&p). I ended up buying the 16032 from a really friendly company in Sweden for a good price. the good £/Euro exchange rate really helped

The proprietor of the shop could not have been more helpful when I had issues with checkout (it wanted a VAT no.) I had registered as a company rather than consumer !
When he found out that I had just retired he also gave me a 'retirement gift '
