[argan]

I bought a licence key 10 days ago for 29$ it was working very well till today.
Something happened and it rolled back to the demo version.
I already got a licence key when i enter that key it does not work anymore.

Please help me asap.

i think that i have just resolved my problem myself

prolly, developers revealed new version of the software and licence keys have been upgraded together with the program
i upgraded my program and it works fine now.

thanks.

Versions before 874 have a problem with occasional license loss, somehow connected with USB-storages used. If you need to have your license re-initialized - please send us an e-mail, mentioning your license number.
