What steps will reproduce the problem?
1. install 8.1.1-1-g5b2d596

What do you expect to happen? What happens instead?
Tellmewhen should load and work. It doesn't. Simple as that. /tmw doesnt work, /tellmewhen doesnt work, it doesnt show up in the interface addons menu, nothing.

I disabled all addons as a test and only enabled TMW, got a new error, still doesnt work.

What version of TellMeWhen are you using? ("The latest" is not a version)
8.1.1-1-g5b2d596

Do you have an error log of what happened?

Please provide any additional information below (including any export strings if applicable; see above.)

Probably an alpha glitch (you forgot to declare something, or whatever). I'm trying the very latest builds because I can't seem to import the icons from my other characters except one. I'll make a new ticket

Are you sure you didn't accidentally install the nolib version?

Apparently I'm just about the only addon author in history who has tried to use forward slashes instead of backslashes in the .toc file. Try the next version in a few mins and see if that works.

Just pushed it. Try gd5421d6 in a minute or two when it's done packaging.

Great! That fixed it. Looking forward to seeing my other ticket looked at.
