Problems compiling after updating UECIDE

[UNF_Michael]

We recently updated UECIDE and can't compile a sketch we had previously been compiling fine using version 0.8.7 The sketch we developed for a college project was compiling and working fine, but we updated the IDE because in the previous version the plugin manager didn't have any of the libraries that the current one has. The version we are currently using is: 0.8.8alpha22. After updating we get the following error below when trying to compile. We have uninstalled the program and deleted the directories and then reinstalled the program completely from scratch. Any help would be hugely appreciated.

We are using a Picadillo 35-T.

It looks to me like you have the old dregs of the old core still hanging around - that is, the old core's libraries, which are incompatible with the current core.

Delete the folder C:\Users\Admin\AppData\Local\UECIDE\cores\chipKIT\libraries and all should be well.

In fact, in general, when doing a version upgrade like this, if things don't work right, it is usually best to delete the entirity of the UECIDE data folder (C:\Users\Admin\AppData\Local\UECIDE) and reinstall all the plugins you need.

Of course, that was exactly the problem. Thank you very much for your quick reply and help.
