[Error] Error while compiling: AntiOfflineRaid.cs(515,80): error CS1525: Unexpected symbol `)'

Since the plugin compiles fine on our site and is provided to you as verified compiling, it sounds like the version you have was modified.

okay i have it sorry

I can't reproduce it. Plugins is compiling fine on our site and locally, so the version you have would have had to have been either modified or corruptedi n some way. The error means that there is incomplete code, causing the plugin to not be compilable.
