Hey @Adám! I had to switch computers at work where my Dyalog REPL was installed (Most of the time I spend here in ppcg is when I'm at work >.>). Can I get my license back, or should I just apply for a new one?

@J.Sallé If your time limit is expired, yes. Otherwise you just install and use your license number.

@Adám Yeah, I'm pretty sure it's expired. I'll apply for a new one later today then

@J.Sallé Maybe next time, keep your downloaded installer.

@Adám yeah, I actually had the downloaded installer in the other computer. Sadly I was only told I would change computers like 2 hours before I had to, so I just saved a bunch of stuff on the fly and didn't remember some of it

@J.Sallé Oh dear. Well, Karen should be in tomorrow morning to renew. What do you do at work, btw?

@Adám The company I work for develops and sells an ERP. In my specific case, I'm developing an OLAP based webapp to generate custom reports from the data in the ERP's DB.

@J.Sallé This may have your interest (sorry, if you've already seen it):

@Adám I have not. I'll take a look :D

@Adám very interesting. The software is amazing.
